Disorder-induced local strain distribution in Y-substituted TmVO4

Yuntian Li, Mark P. Zic, Linda Ye, W. Joe Meese, Pierre Massat, Yanbing Zhu, Rafael M. Fernandes, and Ian R. Fisher

Phys. Rev. B 109, 224201 (2024) - Published 7 June, 2024

Quenched disorder induced by chemical substitution is potentially important in shaping phase diagrams of strongly correlated quantum materials. Chemical substitution results in local strain, and hence conventional theoretical approaches often treat the effects of chemical substitution as random fields. However, this assumption is not fully justified given the long-range nature of strains in solids. Here, the authors explore the disorder effect arising from chemical substitution in TmVO4, an insulator, which undergoes ferroquadrupolar (nematic) order at low temperatures. They find quantitative evidence that the local strain fields are indeed correlated. This result implies that the effects of chemical substitution in all-electronic nematic materials need to be treated with greater degrees of sophistication than the ‘simple’ random field Ising model.

Many-body quantum heat engines based on free fermion systems

Vincenzo Roberto Arezzo, Davide Rossini, and Giulia Piccitto

Phys. Rev. B 109, 224309 (2024) - Published 20 June, 2024

Devising and constructing quantum many-body heat engines is a key challenge of quantum thermodynamics. Most of the research in this field assumes the strokes to be ideal transformations. Here, the authors study the performance of realistic Otto engines with finite-time duration, whose working substance is made of free-fermion systems. They provide analytic expressions for the work and the power delivered through imperfect adiabatic and isochoric strokes. These findings are applied to the case study of an Ising-like quantum Otto cycle.

Universality of the cross-entropy in Z2 symmetric monitored quantum circuits

Maria Tikhanovskaya, Ali Lavasani, Matthew P. A. Fisher, and Sagar Vijay

Phys. Rev. B 109, 224313 (2024) - Published 25 June, 2024

In monitored quantum many-body dynamics, information about the evolving state can “leak” into the measurement record, as quantified by the linear-cross entropy (LXE). Here, the authors show that the LXE serves as an order parameter that also distinguishes various area-law-entangled phases of monitored circuits with a global Ising symmetry. The behavior of the LXE at a critical point separating these phases quantitatively agrees with predictions from the conformal field theory describing this critical point. This connection between out-of-equilibrium dynamics and equilibrium statistical mechanics suggests the possibility of the LXE as a probe of universal critical behavior in other kinds of monitored quantum evolution.

Magnetic versus nonmagnetic polymorphs of RuBr3 under pressure

Bin Shen, Victoria A. Ginga, Angel M. Arévalo-López, Gaston Garbarino, Ece Uykur, Marcos Gonçalves-Faria, Prashanta K. Mukharjee, Philipp Gegenwart, and Alexander A. Tsirlin

Phys. Rev. B 109, 224402 (2024) - Published 3 June, 2024

The delicate balance between magnetic and nonmagnetic states is central to the electronic properties of 4d and 5d honeycomb compounds, including prospective Kitaev materials. External pressure drives the recent Kitaev candidate α-RuBr3 toward the magnetism collapse via structural dimerization, while at lower pressures this material evolves along the boundary between the ferromagnetic and zigzag orders. The alternative chain-like β polymorph is avoided despite its higher thermodynamic stability.

Large anomalous Nernst effect and its bipolarity in the quaternary equiatomic Heusler alloys CrRuXGe (X=Co and Mn)

Amit Chanda, Jadupati Nag, Noah Schulz, Aftab Alam, K. G. Suresh, Manh-Huong Phan, and Hariharan Srikanth

Phys. Rev. B 109, 224415 (2024) - Published 11 June, 2024

Anomalous Nernst effect (ANE)-based thermopiles can be constructed by combining materials with positive and negative ANE coefficients. While most of the magnetic materials show positive ANE, only a limited number of materials exhibit a negative ANE. Furthermore, the majority of the materials showing negative ANE have low Curie temperatures (TC). Here, the authors demonstrate that high-TC quaternary Heusler alloys with large spin polarizations can exhibit both positive and negative ANE coefficients, depending on their chemical compositions, and hence, can be potential candidates for developing efficient room-temperature ANE-based thermopiles.

Laser-enhanced magnetism in SmFeO3

Mohsen Yarmohammadi, Marin Bukov, Vadim Oganesyan, and Michael H. Kolodrubetz

Phys. Rev. B 109, 224417 (2024) - Published 12 June, 2024

Quantum magnetic materials enable the clean realization of many-body states on macroscopic length scales. Dynamic control at terahertz (THz) frequencies is a new frontier for both fundamental physics and applications in quantum technologies. Here, the authors propose THz magnetophononics at low temperatures to control spin excitations in SmFeO3 (a functional rare-earth orthoferrite in spintronics) through lattice excitations (phonons). This approach uncovers a dynamical magnetophononic first-order phase transition that enhances magnetism in SmFeO3.

Magnetic structure and magnetoelectric effect in the centrosymmetric antiferromagnet Cu2(MoO4)(SeO3)

Pharit Piyawongwatthana, Kazuhiro Nawa, Stuart Calder, Daisuke Okuyama, Hung-Cheng Wu, and Taku J. Sato

Phys. Rev. B 109, 224420 (2024) - Published 17 June, 2024

To understand the diverse physics of a quantum magnet, a detailed comprehension of its magnetic properties, particularly the ordered magnetic structure, is essential. This paper demonstrates how sensitive magnetoelectric measurements, realized by detecting SQUID readout phase-locked to the ac electric field excitation, help determine magnetic symmetry. The authors combine neutron diffraction techniques and sensitive magnetoelectric measurements, specifically by measuring the magnetoelectric tensor components, to confirm the crystal’s magnetic symmetry. This approach provides valuable insights into magnetic symmetry and multiferroic phenomena.

Synthesis and superconductivity in (La,Ca)H10 under high pressure

Su Chen, Jianning Guo, Yulong Wang, Xinyue Wu, Wuhao Chen, Xiaoli Huang, and Tian Cui

Phys. Rev. B 109, 224510 (2024) - Published 20 June, 2024

The discovery of binary lanthanum hydrides provides a platform for exploring ternary hydrides with excellent properties. Here, the authors synthesize two lanthanum-calcium hydrides with superconducting critical temperature (Tc) of 247 and 230 K, respectively. The results show that Ca doping has a negligible effect on the Tc of LaH10, but affects the stability of the structure, suggesting that Ca may not be an ideal dopant. This study will help the future search for room-temperature superconductors in more diverse hydride materials.

Quantum degeneracy in mesoscopic matter: Casimir effect and Bose-Einstein condensation

I. Todoshchenko, M. Kamada, J.-P. Kaikkonen, Y. Liao, A. Savin, E. Kauppinen, E. Sergeicheva, and P. J. Hakonen

Phys. Rev. B 109, 224519 (2024) - Published 28 June, 2024

The pressure of ground-state phonons is an acoustic analog to the famous Casimir pressure of zero-point photons. In the experiments here, the authors demonstrate acoustic Casimir pressure in solid monolayer 3He adsorbed on a nanotube. They also demonstrate pushing out thermal phonons with decreasing temperature or length. Another manifestation of quantum degeneracy is Bose-Einstein condensation of vacancies in dimer solid 3He and supersolidity, i.e., nondissipative mass current. The condensation is detected by an increase of dissipation and decoupling of mass.

Evidence for giant surface Dzyaloshinskii-Moriya interaction in the chiral magnetic insulator Cu2OSeO3

Wancong Tan, Haonan Jin, Raymond Fan, Kejing Ran, and Shilei Zhang

Phys. Rev. B 109, L220402 (2024) - Published 5 June, 2024

The depth-dependent skyrmion twisting angle evolution in the chiral magnet Cu2OSeO3 is found to be temperature dependent, which is unexpected from a standard micromagnetic model. Here, the authors experimentally identify that the extra twisting of the topological textures is strongly correlated with the noncollinear electric polarization from the same material, suggesting a new mechanism that can control the magnetic skyrmions.

Gravitational wave analogs in spin nematics and cold atoms

Leilee Chojnacki, Rico Pohle, Han Yan, Yutaka Akagi, and Nic Shannon

Phys. Rev. B 109, L220407 (2024) - Published 14 June, 2024

Gravitational waves, detectable in experiments such as LIGO, are challenging to reproduce. For this reason, it is important to identify analogs in other systems that can be studied on the “lab bench”. Here, the authors show how the Goldstone modes of spin nematic phases, found in magnets and cold atoms, are massless, spin-2 bosons in one-to-one correspondence with the gravitational waves in flat spacetime. Using simulations, the authors further illustrate a procedure for the generation and observation of such waves in a 23Na spinor condensate.

In monitored quantum many-body dynamics, information about the evolving state can “leak” into the measurement record, as quantified by the linear-cross entropy (LXE). Here, the authors show that the LXE serves as an order parameter that also distinguishes various area-law-entangled phases of monitored circuits with a global Ising symmetry. The behavior of the LXE at a critical point separating these phases quantitatively agrees with predictions from the conformal field theory describing this critical point. This connection between out-of-equilibrium dynamics and equilibrium statistical mechanics suggests the possibility of the LXE as a probe of universal critical behavior in other kinds of monitored quantum evolution.

The delicate balance between magnetic and nonmagnetic states is central to the electronic properties of 4d and 5d honeycomb compounds, including prospective Kitaev materials. External pressure drives the recent Kitaev candidate α-RuBr3 toward the magnetism collapse via structural dimerization, while at lower pressures this material evolves along the boundary between the ferromagnetic and zigzag orders. The alternative chain-like β polymorph is avoided despite its higher thermodynamic stability.

Anomalous Nernst effect (ANE)-based thermopiles can be constructed by combining materials with positive and negative ANE coefficients. While most of the magnetic materials show positive ANE, only a limited number of materials exhibit a negative ANE. Furthermore, the majority of the materials showing negative ANE have low Curie temperatures (TC). Here, the authors demonstrate that high-TC quaternary Heusler alloys with large spin polarizations can exhibit both positive and negative ANE coefficients, depending on their chemical compositions, and hence, can be potential candidates for developing efficient room-temperature ANE-based thermopiles.

Quantum magnetic materials enable the clean realization of many-body states on macroscopic length scales. Dynamic control at terahertz (THz) frequencies is a new frontier for both fundamental physics and applications in quantum technologies. Here, the authors propose THz magnetophononics at low temperatures to control spin excitations in SmFeO3 (a functional rare-earth orthoferrite in spintronics) through lattice excitations (phonons). This approach uncovers a dynamical magnetophononic first-order phase transition that enhances magnetism in SmFeO3.

To understand the diverse physics of a quantum magnet, a detailed comprehension of its magnetic properties, particularly the ordered magnetic structure, is essential. This paper demonstrates how sensitive magnetoelectric measurements, realized by detecting SQUID readout phase-locked to the ac electric field excitation, help determine magnetic symmetry. The authors combine neutron diffraction techniques and sensitive magnetoelectric measurements, specifically by measuring the magnetoelectric tensor components, to confirm the crystal’s magnetic symmetry. This approach provides valuable insights into magnetic symmetry and multiferroic phenomena.

The discovery of binary lanthanum hydrides provides a platform for exploring ternary hydrides with excellent properties. Here, the authors synthesize two lanthanum-calcium hydrides with superconducting critical temperature (Tc) of 247 and 230 K, respectively. The results show that Ca doping has a negligible effect on the Tc of LaH10, but affects the stability of the structure, suggesting that Ca may not be an ideal dopant. This study will help the future search for room-temperature superconductors in more diverse hydride materials.

The pressure of ground-state phonons is an acoustic analog to the famous Casimir pressure of zero-point photons. In the experiments here, the authors demonstrate acoustic Casimir pressure in solid monolayer 3He adsorbed on a nanotube. They also demonstrate pushing out thermal phonons with decreasing temperature or length. Another manifestation of quantum degeneracy is Bose-Einstein condensation of vacancies in dimer solid 3He and supersolidity, i.e., nondissipative mass current. The condensation is detected by an increase of dissipation and decoupling of mass.
