Ferromagnetic ferroelectricity due to the Kugel-Khomskii mechanism of orbital ordering assisted by atomic Hund's second rule effects

I. V. Solovyev, R. Ono, and S. A. Nikolaev

Phys. Rev. B 110, 205116 (2024) - Published 7 November, 2024

Ferromagnetic ferroelectricity is a fundamentally interesting and technologically important phenomenon. Nevertheless, the coexistence of ferroelectricity and ferromagnetism is extremely rare in nature. Here, the authors propose how the ferromagnetic ferroelectricity can be induced by the orbital degrees of freedom: if two magnetic sites are connected by the spatial inversion and the system can freely choose which orbitals to occupy, the occupation of unlike orbitals across the inversion center will not only stabilize the ferromagnetic coupling, but also break the inversion symmetry, thus resulting in the ferroelectric-ferromagnetic ground state. The phenomenon is expected in the layered van der Waals ferromagnet VI3, where atomic Hund’s second rule effects provide a sufficient flexibility for the orbital degrees of freedom to form the ordered pattern with broken inversion symmetry.

Tomohiro Soejima (副島智大), Junkai Dong (董焌锴), Taige Wang, Tianle Wang, Michael P. Zaletel, Ashvin Vishwanath, and Daniel E. Parker

Phys. Rev. B 110, 205124 (2024) - Published 12 November, 2024

Anomalous Hall crystals (AHCs) form a new phase of matter with spontaneous crystallization and quantized Hall response. It has been invoked to explain a recent experiment on rhombohedral pentalayer graphene, but a simple conceptual understanding of its existence has been lacking. Here, the authors propose a simple three-patch model that captures how quantum mechanical exchange interactions can stabilize the AHC phase, and apply it to analyze the phenomenology of rhombohedral pentalayer graphene.

Theory of phonon spectroscopy with the quantum twisting microscope

Jiewen Xiao, Erez Berg, Leonid I. Glazman, Francisco Guinea, Shahal Ilani, and Felix von Oppen

Phys. Rev. B 110, 205407 (2024) - Published 5 November, 2024

The quantum twisting microscope, or QTM, is a powerful new scanning probe based on momentum-conserving tunneling across a twistable finite-area interface between van der Waals layers placed on a tip with a flat top and on a substrate. The authors develop here a theory of QTM measurements probing phonon dispersions and electron-phonon couplings of van der Waals materials. The results inform the quest to understand superconductivity in twisted bilayer graphene and provide a case study for QTM investigations of collective modes.

Charge density waves with nontrivial orbital textures in rare earth tritellurides

Sergey Alekseev, Sayed Ali Akbar Ghorashi, Rafael M. Fernandes, and Jennifer Cano

Phys. Rev. B 110, 205103 (2024) - Published 4 November, 2024

Recent experiments on the rare-earth tritellurides RTe3 reveal unconventional collective modes in the charge density wave (CDW) state, suggesting symmetry breaking beyond that imposed by the CDW wave vector. Here, the authors develop a CDW Ginzburg-Landau theory that incorporates nontrivial orbital order, allowing for solutions in which two CDWs with distinct orbital characters coexist. The resulting CDW pattern exhibits an orbital texture that can break mirror and/or inversion symmetry.

(La,Sr)2NiO3: An antiferromagnetic Mott insulator capable of doping

Xiaochao Wang, Paul Worm, Ying Gao, Wenfeng Wu, Nan Liu, Yongqiang Wang, Karsten Held, and Liang Si

Phys. Rev. B 110, 205110 (2024) - Published 5 November, 2024

The synthesis and study of superconducting nickelate oxides represents an exciting frontier in condensed matter physics. Here, the authors investigate the structural, electronic, and magnetic properties of the nickelates (La,Sr)2NiO4 and their reduced form, (La,Sr)2NiO3. Using density functional theory (DFT) and dynamical mean-field theory (DMFT) calculations, they demonstrate that chemical reduction with CaH2 or NaH leads to a 3d9 electronic configuration, resulting in (La0.5Sr0.5)2NiO3 as a single-band antiferromagnetic Mott insulator. Hole doping disrupts this antiferromagnetic order, driving the material metallic, suggesting the intriguing potential for p-wave superconductivity in these nickelate systems.

Inducing topological flat bands in bilayer graphene with electric and magnetic superlattices

Daniel Seleznev, Jennifer Cano, and David Vanderbilt

Phys. Rev. B 110, 205115 (2024) - Published 6 November, 2024

Topological flat bands offer a unique opportunity to study the interplay between electronic correlations and band topology, giving rise to correlation-induced topological phases, such as fractional quantum Hall states. Here, the authors explore the generation of topological flat bands in Bernal-stacked bilayer graphene via application of commensurate electric and magnetic superlattices. Tuning these superlattices reveals their versatility in producing topological flat bands, including those with high Chern numbers. The authors additionally propose a novel, tunable setup involving magnetoelectrics and type-II superconductors to generate such superlattices.

Bonding states underpinning structural transitions in IrTe2 observed with micro-ARPES

C. W. Nicholson, M. D. Watson, A. Pulkkinen, M. Rumo, G. Kremer, K. Y. Ma, F. O. von Rohr, C. Cacho, and C. Monney

Phys. Rev. B 110, 205123 (2024) - Published 12 November, 2024

Structural phase transitions of debated origin occur at low temperature in IrTe2. This results in the formation of stripes of atomic dimers that drastically lowers the symmetry of the system. As a consequence, many domains with different orientations and periodicity coexist, making studies complicated. Here, the authors take advantage of micro-spot photoemission spectroscopy to isolate the electronic structure of each phase, thereby revealing the electronic orbitals that stabilize the phase transitions.

Stability of anomalous Hall crystals in multilayer rhombohedral graphene

Zhihuan Dong, Adarsh S. Patri, and T. Senthil

Phys. Rev. B 110, 205130 (2024) - Published 14 November, 2024

Amidst recent burning interest in quantum anomalous Hall phenomena in pentalayer graphene, the authors provide here an elegant understanding for existing numerical mean field results. Beyond mean field, the authors propose the picture of “moiré-enabled Hall crystals”, emphasizing the crucial role of a moiré potential even when weak. The authors provide a connection between electronic crystals and the superconducting Little-Parks effect to explicitly demonstrate the quantization of Chern number associated with spontaneous crystalline order, analogous to quantization of vorticity in a superconducting ring under a background magnetic field.

Altermagnetism on the Shastry-Sutherland lattice

Francesco Ferrari and Roser Valentí

Phys. Rev. B 110, 205140 (2024) - Published 19 November, 2024

Altermagnetism is an unconventional form of magnetic order characterized by spin-split electronic bands and zero net magnetization. Here, the authors utilize a variational Monte Carlo approach to reveal the emergence of d-wave altermagnetism in the Hubbard model on the Shastry-Sutherland lattice and demonstrate how strong electronic correlations manifest in the metal-insulator transition. The calculation of photoemission spectral functions highlights the presence of altermagnetic Zeeman splitting, also in the Mott insulating phase (and upon doping).

Flat plane based double-counting free and parameter free many-body DFT+U

Andrew C. Burgess and David D. O'Regan

Phys. Rev. B 110, 205150 (2024) - Published 26 November, 2024

The authors construct here a DFT+U type corrective functional using exact quantum conditions instead of the Hubbard model. DFT+U is widely used in density functional theory, particularly for transition-metal and rare-earth bearing materials. In several small molecules, providing stringent, near-ideal test cases, traditional DFT+U worsens the total energy. The introduced mBLOR functional, with parameters calculated in situ, instead reduces errors significantly. It incorporates simplified interorbital error corrections, is free of double-counting approximations, and opens gaps without unphysical symmetry breaking.

Simulating electron-vibron energy transfer with quantum dots and resonators

C. Hermansen, M. Caltapanides, V. Meden, and J. Paaske

Phys. Rev. B 110, 205424 (2024) - Published 20 November, 2024

Quantum dot arrays offer a natural representation of the interacting π-electron system of small hydrocarbon molecules. This paper proposes an extension of quantum dot simulators to include also the molecular vibrational modes represented by single-mode microwave resonators coupled capacitively to the quantum dots. The authors calculate the gate-tunable energy transfer from a voltage-biased triple quantum dot system to a single damped resonator mode and find a pronounced maximum near an interference node in the electrical current.

Passivity constraints on the relations between transmission, reflection, and absorption eigenvalues

Cheng Guo and Shanhui Fan

Phys. Rev. B 110, 205431 (2024) - Published 26 November, 2024

Passivity is a fundamental property of many physical systems, characterizing their inability to generate energy. The authors investigate here passivity constraints on the relations between transmission, reflection, and absorption eigenvalues in linear time-invariant systems. The analysis shows that the set of allowable eigenvalue combinations forms a convex polyhedron. The theory reveals a surprising connection to Horn’s inequalities, a fundamental result in matrix theory. It has significant implications for the design and optimization of passive devices in optics, acoustics, and mesoscopic physics.

Interplay of superexchange and vibronic effects in the hidden order of Ba2MgReO6 from first principles

Dario Fiore Mosca, Cesare Franchini, and Leonid V. Pourovskii

Phys. Rev. B 110, L201101 (2024) - Published 4 November, 2024

In heavy transition metal oxides, electronic correlation and strong spin-orbit coupling can give rise to “hidden order”, with multipolar order parameters. Here, the authors investigate the origin of the unusual quadrupolar and magnetic phases in the double perovskite Ba2MgReO6. They derive its low-energy Hamiltonian from first principles and show that its antiferroic order of x2-y2 quadrupoles and a low-temperature canted antiferromagnetic phase emerge from the interplay between electron-lattice coupling and multipolar superexchange interactions.

Juan Felipe Mendez-Valderrama, Sunghoon Kim, and Debanjan Chowdhury

Phys. Rev. B 110, L201105 (2024) - Published 14 November, 2024

Recent experiments in moiré transition metal dichalcogenide (TMD) materials have uncovered a number of remarkable correlation-induced phases with nontrivial band topology. Here, the authors investigate topological mixed-valence and Kondo insulators in this platform at a commensurate band filling. This study highlights the distinct roles of Mottness and topology in shaping the interaction-induced phase diagram, and proposes a possible route toward realizing exotic fractionalized insulators.

Twisted coupled wire model for a moiré sliding Luttinger liquid

Yichen Hu, Yuanfeng Xu, and Biao Lian

Phys. Rev. B 110, L201106 (2024) - Published 14 November, 2024

The authors propose here a twisted bilayer 2D array in a coupled-wire model to characterize the anisotropic Luttinger Liquid behavior observed in twisted bilayer WTe2. Solving this model using transfer matrix method gives quasi-1D moiré electron bands at small twist angles, which have a significantly reduced Luttinger parameter when interaction is taken into account. This indicates strong correlation effects and leads to the existence of a sliding Luttinger liquid (SLL) regime in twisted bilayer WTe2.

Deconfined quantum criticality in Ising gauge theory entangled with single-component fermions

Umberto Borla, Snir Gazit, and Sergej Moroz

Phys. Rev. B 110, L201110 (2024) - Published 19 November, 2024

Investigating novel manifestations of quantum criticality is central to modern theoretical condensed matter physics. Here, the authors unveil the exotic quantum phase diagram of a two-dimensional system of single-component fermions, minimally coupled to dynamical Ising gauge fields. With state-of-the-art numerical methods, the authors detect a robust quantum critical line, where gauge confinement and translation symmetry breaking occur simultaneously. The authors conjecture a u(1) deconfined criticality scenario, and propose a corresponding low-energy effective field theory of the exotic quantum critical point.

Supercell Wannier functions and a faithful low-energy model for Bernal bilayer graphene

Ammon Fischer, Lennart Klebl, Dante M. Kennes, and Tim O. Wehling

Phys. Rev. B 110, L201113 (2024) - Published 22 November, 2024

The authors derive here a minimal low-energy model for Bernal bilayer graphene and related rhombohedral graphene multilayers at low electronic densities. They construct valley-polarized Wannier orbitals defined in real-space supercells of the original primitive cell. By projecting realistic Coulomb interactions to the supercell Wannier basis, the authors demonstrate that Bernal bilayer graphene is in the weakly coupled regime. The resulting low-energy lattice models for rhombohedral graphene stacks pave the way for unbiased characterization of many-body phases in multilayer graphene.

Phys. Rev. B 110, L201118 (2024) - Published 26 November, 2024

Nonlinear photocurrents in topological semimetals encode quantum geometric characters of Bloch wavefunctions and band topology, and offer a new opportunity for advanced photovoltaics. Here, the authors characterize the nonlinear photoconductivities of chiral multifold semimetal CoSi through a refined terahertz emission spectroscopy analysis. The results reveal a large linear shift conductivity and confirm a giant nonquantized circular injection conductivity in the mid-infrared range. Bulk transverse injection currents and relatively weak photon drag effect are also identified.

Nearly quantized Born effective charges as probes for the topological phase transition in the Haldane and Kane-Mele models

Paolo Fachin, Francesco Macheda, Paolo Barone, and Francesco Mauri

Phys. Rev. B 110, L201405 (2024) - Published 13 November, 2024

The authors introduce here a novel method for examining transitions between distinct topological phases by analyzing vibrational resonances in infrared spectra. In the prototypical Haldane and Kane-Mele models, the Born effective charges, which measure the interaction between infrared light and phonons, are nearly quantized and exhibit a sharp change that coincides with the topological phase transition. In the Haldane model, which breaks time-reversal symmetry, a similar discontinuous shift is also observed in the chiral phonon splitting.

The synthesis and study of superconducting nickelate oxides represents an exciting frontier in condensed matter physics. Here, the authors investigate the structural, electronic, and magnetic properties of the nickelates (La,Sr)2NiO4 and their reduced form, (La,Sr)2NiO3.

Hole doping disrupts this antiferromagnetic order, driving the material metallic, suggesting the intriguing potential for p-wave superconductivity in these nickelate systems.

Phys. Rev. B 110, 205115 (2024) - Published 6 November, 2024

Topological flat bands offer a unique opportunity to study the interplay between electronic correlations and band topology, giving rise to correlation-induced topological phases, such as fractional quantum Hall states. Here, the authors explore the generation of topological flat bands in Bernal-stacked bilayer graphene via application of commensurate electric and magnetic superlattices. Tuning these superlattices reveals their versatility in producing topological flat bands, including those with high Chern numbers. The authors additionally propose a novel, tunable setup involving magnetoelectrics and type-II superconductors to generate such superlattices.

Ferromagnetic ferroelectricity due to the Kugel-Khomskii mechanism of orbital ordering assisted by atomic Hund's second rule effects

I. V. Solovyev, R. Ono, and S. A. Nikolaev

Phys. Rev. B 110, 205116 (2024) - Published 7 November, 2024

Ferromagnetic ferroelectricity is a fundamentally interesting and technologically important phenomenon. Nevertheless, the coexistence of ferroelectricity and ferromagnetism is extremely rare in nature. Here, the authors propose how the ferromagnetic ferroelectricity can be induced by the orbital degrees of freedom: if two magnetic sites are connected by the spatial inversion and the system can freely choose which orbitals to occupy, the occupation of unlike orbitals across the inversion center will not only stabilize the ferromagnetic coupling, but also break the inversion symmetry, thus resulting in the ferroelectric-ferromagnetic ground state. The phenomenon is expected in the layered van der Waals ferromagnet VI3, where atomic Hund’s second rule effects provide a sufficient flexibility for the orbital degrees of freedom to form the ordered pattern with broken inversion symmetry.

Phys. Rev. B 110, 205123 (2024) - Published 12 November, 2024

Structural phase transitions of debated origin occur at low temperature in IrTe2. This results in the formation of stripes of atomic dimers that drastically lowers the symmetry of the system. As a consequence, many domains with different orientations and periodicity coexist, making studies complicated. Here, the authors take advantage of micro-spot photoemission spectroscopy to isolate the electronic structure of each phase, thereby revealing the electronic orbitals that stabilize the phase transitions.

Anomalous Hall crystals in rhombohedral multilayer graphene. II. General mechanism and a minimal model

Phys. Rev. B 110, 205124 (2024) - Published 12 November, 2024

Anomalous Hall crystals (AHCs) form a new phase of matter with spontaneous crystallization and quantized Hall response. It has been invoked to explain a recent experiment on rhombohedral pentalayer graphene, but a simple conceptual understanding of its existence has been lacking. Here, the authors propose a simple three-patch model that captures how quantum mechanical exchange interactions can stabilize the AHC phase, and apply it to analyze the phenomenology of rhombohedral pentalayer graphene.

Amidst recent burning interest in quantum anomalous Hall phenomena in pentalayer graphene, the authors provide here an elegant understanding for existing numerical mean field results. Beyond mean field, the authors propose the picture of “moiré-enabled Hall crystals”, emphasizing the crucial role of a moiré potential even when weak. The authors provide a connection between electronic crystals and the superconducting Little-Parks effect to explicitly demonstrate the quantization of Chern number associated with spontaneous crystalline order, analogous to quantization of vorticity in a superconducting ring under a background magnetic field.

Altermagnetism is an unconventional form of magnetic order characterized by spin-split electronic bands and zero net magnetization. Here, the authors utilize a variational Monte Carlo approach to reveal the emergence of d-wave altermagnetism in the Hubbard model on the Shastry-Sutherland lattice and demonstrate how strong electronic correlations manifest in the metal-insulator transition. The calculation of photoemission spectral functions highlights the presence of altermagnetic Zeeman splitting, also in the Mott insulating phase (and upon doping).

Andrew C. Burgess and David D. O'Regan

Phys. Rev. B 110, 205150 (2024) - Published 26 November, 2024

The authors construct here a DFT+U type corrective functional using exact quantum conditions instead of the Hubbard model. DFT+U is widely used in density functional theory, particularly for transition-metal and rare-earth bearing materials. In several small molecules, providing stringent, near-ideal test cases, traditional DFT+U worsens the total energy. The introduced mBLOR functional, with parameters calculated in situ, instead reduces errors significantly. It incorporates simplified interorbital error corrections, is free of double-counting approximations, and opens gaps without unphysical symmetry breaking.

The quantum twisting microscope, or QTM, is a powerful new scanning probe based on momentum-conserving tunneling across a twistable finite-area interface between van der Waals layers placed on a tip with a flat top and on a substrate. The authors develop here a theory of QTM measurements probing phonon dispersions and electron-phonon couplings of van der Waals materials. The results inform the quest to understand superconductivity in twisted bilayer graphene and provide a case study for QTM investigations of collective modes.

Phys. Rev. B 110, 205431 (2024) - Published 26 November, 2024

Passivity is a fundamental property of many physical systems, characterizing their inability to generate energy. The authors investigate here passivity constraints on the relations between transmission, reflection, and absorption eigenvalues in linear time-invariant systems. The analysis shows that the set of allowable eigenvalue combinations forms a convex polyhedron. The theory reveals a surprising connection to Horn’s inequalities, a fundamental result in matrix theory. It has significant implications for the design and optimization of passive devices in optics, acoustics, and mesoscopic physics.
