Symmetry-broken metallic orders in spin-orbit-coupled Bernal bilayer graphene

Jin Ming Koh, Alex Thomson, Jason Alicea, and Étienne Lantagne-Hurtubise

Phys. Rev. B 110, 245118 (2024) - Published 9 December, 2024

Here, the authors investigate the phase diagram of Bernal bilayer graphene in the presence of long-range Coulomb interactions, short-range Hund’s coupling, and proximity-induced Ising spin-orbit coupling using self-consistent Hartree-Fock calculations. Their analysis reveals a rich landscape of symmetry-broken phases resulting from the interplay between these three ingredients, which is tunable via doping and applied displacement field. Particular focus is placed on spin-canted and intervalley coherent states that may hold the key to understanding spin-orbit-enabled superconductivity observed in this platform.

Quantum geometry and nonlinear optical responses in rhombohedral trilayer graphene

Abigail Postlewaite, Arpit Raj, Swati Chaudhary, and Gregory A. Fiete

Phys. Rev. B 110, 245122 (2024) - Published 10 December, 2024

Multilayered graphene systems provide a highly tunable platform to study quantum geometric effects. Here, the authors show that the quantum geometry of electronic bands in rhombohedral trilayer graphene leads to a large shift-current response which can be tuned by applying a displacement field perpendicular to the layers. The authors compare the response with Bernal stacked bilayer graphene and find additional features arising due to the confluence of quantum geometry and the multiband nature of rhombohedral trilayer graphene.

Quantum embedding study of strain- and electric-field-induced Stark effects on the NV center in diamond

Gabriel I. López-Morales, Joanna M. Zajac, Johannes Flick, Carlos A. Meriles, and Cyrus E. Dreyer

Phys. Rev. B 110, 245127 (2024) - Published 13 December, 2024

The negatively charged nitrogen vacancy (NV) center in diamond is a well-known color center with interesting applications in nanoscale sensing and quantum metrology, due to its high sensitivity to minute local electric, magnetic, and strain fields. Motivated by these applications of the this center, the authors employ here first-principles calculations based on quantum embedding to derive a many-body description of its excited-state dipole couplings and strain susceptibilities, which underlie the electric field and strain induced Stark effects.

Spectral density and sum rules for second-order response functions

Barry Bradlyn and Peter Abbamonte

Phys. Rev. B 110, 245132 (2024) - Published 18 December, 2024

Sum rules for response functions represent some of the few exact results in many-body physics, relating the dynamical response functions to equilibrium ground state properties. To date, however, sum rules have been examined primarily for linear response functions. In this work, the authors introduce a spectral density representation for second-order response functions, using it to systematically derive families of sum rules, including a nonlinear extension of the well-known f-sum rule. This work places important constraints on future nonlinear spectroscopic experiments.

Photoinduced phase transition on black samarium monosulfide

Hiroshi Watanabe, Yusuke Takeno, Yusuke Negoro, Ryohei Ikeda, Yuria Shibata, Yitong Chen, Takuto Nakamura, Kohei Yamagami, Yasuyuki Hirata, Yujun Zhang, Ryunosuke Takahashi, Hiroki Wadati, Kenji Tamasaku, Keiichiro Imura, Hiroyuki S. Suzuki, Noriaki K. Sato, and Shin-ichi Kimura

Phys. Rev. B 110, 245133 (2024) - Published 19 December, 2024

Samarium monosulfide (SmS) is known to present a pressure-induced phase transition (BGT) from a black-colored insulator (BI) to a golden yellow colored metal (GM). To investigate the role of excitonic instability in BGT, the authors measure here the changes in electronic structure and lattice constant after pulse-laser excitations. The photoexcitation creates a photoinduced phase slightly different from the BI state, but utterly different from the GM state, suggesting that BGT requires effects other than the appearance of excitons.

Theories for charge-driven nematicity in kagome metals

Francesco Grandi, Michael A. Sentef, Dante M. Kennes, and Ronny Thomale

Phys. Rev. B 110, 245138 (2024) - Published 24 December, 2024

Nematicity, the broken rotational symmetry of a lattice’s point group, is often linked to unconventional superconductivity. This work presents two theories for the nematic behavior in kagome metals. One theory suggests a d-wave charge Pomeranchuk instability, while the other attributes nematicity to fluctuations in one-dimensional charge order observed experimentally. Unlike iron-based superconductors, where spin-fluctuations drive nematicity, the kagome metals’ nematic tendencies are likely induced by charge fluctuations, offering a distinct mechanism for this behavior.

Identifying the topological order of quantized half-filled Landau levels through their daughter states

Evgenii Zheltonozhskii, Ady Stern, and Netanel H. Lindner

Phys. Rev. B 110, 245140 (2024) - Published 26 December, 2024

Identifying the topological order of potentially non-Abelian half-filled quantum Hall states is notoriously difficult. While “daughter states” have been proposed as a signature, existing calculations were incomplete. This work provides a comprehensive framework based on hierarchical construction and flux attachment, predicting daughter states for all candidate parent states. Observing daughter states on both sides of half-filling enables the identification of the parent’s topological order. Applied to experiments, this reveals a Pfaffian state in wide-well GaAs and a Pfaffian/anti-Pfaffian sequence in graphene, a contrast to PH-Pfaffian in narrow-well GaAs.

Nuclear spin-spin interactions in CdTe probed by zero- and ultralow-field optically detected NMR

V. M. Litvyak, P. S. Bazhin, R. André, M. Vladimirova, and K. V. Kavokin

Phys. Rev. B 110, 245303 (2024) - Published 9 December, 2024

Nuclear spins occupying adjacent lattice sites in crystalline solids are often coupled by indirect interactions mediated by valence electrons. If the abundance of magnetic isotopes in the crystal is low, these interactions bind nuclear spins into small clusters. Zero or ultralow magnetic field NMR spectra of CdTe, detected via warm-up of the optically cooled nuclear spin system by oscillating magnetic fields, reveal pseudodipole and scalar interactions within clusters composed of up to 4 spins of magnetic isotopes of Cd and Te.

Going beyond Landauer scattering theory to describe spatially resolved nonlocal heating and cooling in quantum thermoelectrics

Nico G. Leumer, Denis M. Basko, Rodolfo A. Jalabert, Dietmar Weinmann, and Robert S. Whitney

Phys. Rev. B 110, 245402 (2024) - Published 2 December, 2024

Nanoscale thermometry is starting to reveal answers to the 40 year old question of where dissipation (Joule heating) occurs when an electric current flows through a nanostructure. Since the 1980s, Landauer scattering theory has only said that it happens “somewhere” in the leads connected to that nanostructure. This theoretical work goes beyond this by modeling spatially resolved Joule heating and thermoelectric cooling. It predicts an unexpected nonlocality in heat transfer between electrons and phonons, with heating and cooling spots at a finite distance from the voltage drop that causes them.

Quasinormal mode theory for multiresonant metasurfaces with superwavelength periodicity involving two-dimensional materials

Thomas Christopoulos, Georgios Nousios, Emmanouil E. Kriezis, and Odysseas Tsilipakos

Phys. Rev. B 110, 245407 (2024) - Published 6 December, 2024

Contemporary photonic resonant systems are non-Hermitian, exhibiting radiation leakage and loss. By specifying the quasinormal modes (QNMs) that they support, one can obtain physical insight into the light-matter interaction processes and construct modal analysis tools that allow for the efficient calculation of their spectral response. The authors develop here a QNM framework for non-Hermitian periodic resonant systems that involves bulk and two-dimensional materials. It is employed to study multiresonant metasurfaces with superwavelength periodicity and is proven highly efficient and accurate.

Electrically defined quantum dots for bosonic excitons

Deepankur Thureja, F. Emre Yazıcı, Tomasz Smoleński, Martin Kroner, David J. Norris, and Atac İmamoǧlu

Phys. Rev. B 110, 245425 (2024) - Published 27 December, 2024

Solid-state single-photon sources based on quantum dots have found numerous applications in fields ranging from quantum information processing to commercial displays. A major current limitation is the large inhomogeneity in, and lack of tunability of, the photon energy. Here, the authors demonstrate electrically defined quantum dots for excitons in monolayer semiconductors, where the exciton, and consequently the photon emission, energy can be controlled using applied gate voltages. Resonance fluorescence measurements show strong spectral jumps and blinking of exciton emission, verifying their zero-dimensional nature.

(H,Li)6Ru2O6: A possible zero-field Ru3+-based Kitaev quantum spin liquid

Sanjay Bachhar, M. Baenitz, Hubertus Luetkens, John Wilkinson, Sumiran Pujari, and A. V. Mahajan

Phys. Rev. B 110, L241102 (2024) - Published 2 December, 2024

This is a comprehensive study of the Ru3+-based Kitaev honeycomb compound (H,Li)6Ru2O6 (HLRO), combining magnetization (M), magnetic specific heat (Cm), and local probes (muon spin relaxation and magnetic resonance). There is clear evidence of a Kitaev quantum spin liquid (KQSL) state. M, Cm, and magnetic fluctuations (1/T1) exhibit scaling behavior. The Cm scaling is in good agreement with theory [PRX 11, 011034 (2021)]. A two-step entropy release is taken as a signature of Majorana fermions. HLRO is a realization of a KQSL without magnetic order in zero field, unlike 𝛼-RuCl3.

Importance of electron-phonon coupling near the electron-liquid to Wigner-crystal transition in two-dimensional atomically thin materials

Tixuan Tan, Vladimir Calvera, and Steven A. Kivelson

Phys. Rev. B 110, L241104 (2024) - Published 10 December, 2024

Motivated by recent experiments on atomically thin transition metal dichalcogenides (TMDs), the authors explore here the role of electron-phonon coupling in the location of the fluid-to-liquid transition point of electrons. They highlight that phonons (illustrated as the blue background) can gain more energy when electrons form a Wigner crystal compared to when they are in a liquid state. Their findings demonstrate that this effect significantly affects TMDs and other atomically thin materials, while its impact remains negligible in quantum wells. This is consistent with previous experimental results.

Experimental observation of boundary flat bands with topological spin textures

Yuanchuan Biao, Zhongbo Yan, and Rui Yu

Phys. Rev. B 110, L241110 (2024) - Published 24 December, 2024

The spin polarization of a boundary flat band (BFB) protected by chiral symmetry is typically fixed. The authors experimentally demonstrate here the realization of BFBs with momentum-dependent spin polarizations, exhibiting nontrivial topological windings across the boundary Brillouin zone in a circuit system. The so-called subchiral symmetry is the key symmetry responsible for the emergence of these additional topological properties. These findings establish BFBs as a promising new platform for exploring flat-band physics.

Continuous Wigner-Mott transitions at ν=1/5

Thomas G. Kiely and Debanjan Chowdhury

Phys. Rev. B 110, L241112 (2024) - Published 26 December, 2024

Interactions and fluctuations can drastically change the nature of phases and phase transitions in electronic materials. Here, the authors provide numerical evidence for a continuous quantum phase transition between a normal metal and a crystalline insulator, which challenges physicists’ standard theories for quantum phase transitions and demands novel explanations. Inspired by experiments in moiré quantum simulators and using sophisticated numerics, the authors study the transition from a crystal of spatially separated electron pairs to a metal as the interaction strength is reduced at a fixed low filling.

Competing magnetic states on the surface of multilayer ABC-stacked graphene

Lauro B. Braz, Tanay Nag, and Annica M. Black-Schaffer

Phys. Rev. B 110, L241401 (2024) - Published 3 December, 2024

The discovery of novel magnetic phases on the surface of rhombohedral graphene multilayers presents exciting potential for novel physics. Here, the authors demonstrate that the topological surface states of ABC-stacked graphite host competing magnetic states arising from intravalley and intervalley electron scattering. Electron-electron interactions generate incommensurate magnetic states with notably long spin-spin relaxation times at charge neutrality. These findings suggest that rhombohedral graphite likely hosts a plethora of different magnetic states.

Topological classification of one-dimensional chiral symmetric interfaces

Harry MullineauxSanders and Bernd Braunecker

Phys. Rev. B 110, L241409 (2024) - Published 20 December, 2024

The placement of an interface of scatterers into a substrate allows the engineering of low-dimensional topological phases through interface modes. The different dimensionality of interface and substrate, as well as the spatial extent of the interface modes, impedes a straightforward topological classification, though, and makes some classification schemes fail. The authors provide here a proof that the computationally easily accessible Green’s function tuned to the interface provides the exact classification, by accurately disentangling the topological properties of substrate and interface.

Light-controlled terahertz plasmonic time-varying media: Momentum gaps, entangled plasmon pairs, and pulse-induced time reversal

Egor I. Kiselev, Yiming Pan, and Netanel H. Lindner

Phys. Rev. B 110, L241411 (2024) - Published 30 December, 2024

The authors suggest here a new method to excite terahertz plasmons in two-dimensional Dirac materials with amplitude modulated high frequency light. This method does not make use of THz sources, but, in fact, could be used to generate THz radiation. Additionally, they show that their method can be used to create entangled plasmon pairs, to amplify plasmons, and to actively control them, e.g. to time-mirror plasmonic waves.

Multilayered graphene systems provide a highly tunable platform to study quantum geometric effects. Here, the authors show that the quantum geometry of electronic bands in rhombohedral trilayer graphene leads to a large shift-current response which can be tuned by applying a displacement field perpendicular to the layers. The authors compare the response with Bernal stacked bilayer graphene and find additional features arising due to the confluence of quantum geometry and the multiband nature of rhombohedral trilayer graphene.

The negatively charged nitrogen vacancy (NV) center in diamond is a well-known color center with interesting applications in nanoscale sensing and quantum metrology, due to its high sensitivity to minute local electric, magnetic, and strain fields. Motivated by these applications of the this center, the authors employ here first-principles calculations based on quantum embedding to derive a many-body description of its excited-state dipole couplings and strain susceptibilities, which underlie the electric field and strain induced Stark effects.

Spectral density and sum rules for second-order response functions

Phys. Rev. B 110, 245132 (2024) - Published 18 December, 2024

Sum rules for response functions represent some of the few exact results in many-body physics, relating the dynamical response functions to equilibrium ground state properties. To date, however, sum rules have been examined primarily for linear response functions. In this work, the authors introduce a spectral density representation for second-order response functions, using it to systematically derive families of sum rules, including a nonlinear extension of the well-known f-sum rule. This work places important constraints on future nonlinear spectroscopic experiments.

Photoinduced phase transition on black samarium monosulfide

Phys. Rev. B 110, 245133 (2024) - Published 19 December, 2024

Samarium monosulfide (SmS) is known to present a pressure-induced phase transition (BGT) from a black-colored insulator (BI) to a golden yellow colored metal (GM). To investigate the role of excitonic instability in BGT, the authors measure here the changes in electronic structure and lattice constant after pulse-laser excitations. The photoexcitation creates a photoinduced phase slightly different from the BI state, but utterly different from the GM state, suggesting that BGT requires effects other than the appearance of excitons.

Phys. Rev. B 110, 245138 (2024) - Published 24 December, 2024

Nematicity, the broken rotational symmetry of a lattice’s point group, is often linked to unconventional superconductivity. This work presents two theories for the nematic behavior in kagome metals. One theory suggests a d-wave charge Pomeranchuk instability, while the other attributes nematicity to fluctuations in one-dimensional charge order observed experimentally. Unlike iron-based superconductors, where spin-fluctuations drive nematicity, the kagome metals’ nematic tendencies are likely induced by charge fluctuations, offering a distinct mechanism for this behavior.

Identifying the topological order of quantized half-filled Landau levels through their daughter states

Phys. Rev. B 110, 245140 (2024) - Published 26 December, 2024

Identifying the topological order of potentially non-Abelian half-filled quantum Hall states is notoriously difficult. While “daughter states” have been proposed as a signature, existing calculations were incomplete. This work provides a comprehensive framework based on hierarchical construction and flux attachment, predicting daughter states for all candidate parent states. Observing daughter states on both sides of half-filling enables the identification of the parent’s topological order. Applied to experiments, this reveals a Pfaffian state in wide-well GaAs and a Pfaffian/anti-Pfaffian sequence in graphene, a contrast to PH-Pfaffian in narrow-well GaAs.

Nuclear spins occupying adjacent lattice sites in crystalline solids are often coupled by indirect interactions mediated by valence electrons. If the abundance of magnetic isotopes in the crystal is low, these interactions bind nuclear spins into small clusters. Zero or ultralow magnetic field NMR spectra of CdTe, detected via warm-up of the optically cooled nuclear spin system by oscillating magnetic fields, reveal pseudodipole and scalar interactions within clusters composed of up to 4 spins of magnetic isotopes of Cd and Te.

Nanoscale thermometry is starting to reveal answers to the 40 year old question of where dissipation (Joule heating) occurs when an electric current flows through a nanostructure. Since the 1980s, Landauer scattering theory has only said that it happens “somewhere” in the leads connected to that nanostructure. This theoretical work goes beyond this by modeling spatially resolved Joule heating and thermoelectric cooling. It predicts an unexpected nonlocality in heat transfer between electrons and phonons, with heating and cooling spots at a finite distance from the voltage drop that causes them.

Phys. Rev. B 110, 245407 (2024) - Published 6 December, 2024

Contemporary photonic resonant systems are non-Hermitian, exhibiting radiation leakage and loss. By specifying the quasinormal modes (QNMs) that they support, one can obtain physical insight into the light-matter interaction processes and construct modal analysis tools that allow for the efficient calculation of their spectral response. The authors develop here a QNM framework for non-Hermitian periodic resonant systems that involves bulk and two-dimensional materials. It is employed to study multiresonant metasurfaces with superwavelength periodicity and is proven highly efficient and accurate.

Solid-state single-photon sources based on quantum dots have found numerous applications in fields ranging from quantum information processing to commercial displays. A major current limitation is the large inhomogeneity in, and lack of tunability of, the photon energy. Here, the authors demonstrate electrically defined quantum dots for excitons in monolayer semiconductors, where the exciton, and consequently the photon emission, energy can be controlled using applied gate voltages. Resonance fluorescence measurements show strong spectral jumps and blinking of exciton emission, verifying their zero-dimensional nature.
