Inverse magnetoconductance design by automatic differentiation

Yuta Hirasaki, Koji Inui, and Eiji Saitoh

Phys. Rev. B 110, 214201 (2024) - Published 6 December, 2024

Magnetoconductance in thin wires often displays complex patterns due to the quantum interference of conduction electrons, which reflects the microscopic structures of the wires. The authors propose here a method to automatically determine the microscopic structure of a thin wire that reproduces a desired magnetoconductance pattern, leveraging automatic differentiation. The authors identify multiple microscopic structures that accurately reproduce a given magnetoconductance pattern, and discuss techniques for selecting experimentally feasible microscopic structures.

Nonlinear finite-difference time-domain method for exciton-polaritons: Application to saltatory conduction in polariton neurons

K. Dini, H. Sigurðsson, N. W. E. Seet, P. M. Walker, and T. C. H. Liew

Phys. Rev. B 110, 214303 (2024) - Published 4 December, 2024

Polariton neurons allow exciton-polaritons to transport information using a successive local switching in analogy to action potentials in biological neurons. The authors show here an analogue of saltatory conduction for enhancing signal speeds: by connecting bistable nodes with waveguides, polariton signal speeds can be increased tenfold. The modeling of this system requires a new theoretical tool: nonlinear finite-difference time-domain simulation, which accounts for the propagation of light in the full three-dimensional nanostructure together with nonlinear exciton-exciton scattering using Maxwell-Bloch equations.

Michael L. Wall, Aidan Reilly, John S. Van Dyke, Collin Broholm, and Paraj Titum

Phys. Rev. B 110, 214402 (2024) - Published 2 December, 2024

Quantum tensor networks enable efficient representation of low-energy quantum states on quantum computers by minimizing qubit resources through qubit reuse. Existing algorithms are limited to extracting simple, static properties like total magnetization. The authors present here two new efficient quantum algorithms for computing more complex dynamic correlation functions critical to modeling neutron scattering experiments and apply them to simulate properties of magnetic molecules.

Complex orders and chirality in the classical Kitaev-Γ model

P. Peter Stavropoulos, Yang Yang, Ioannis Rousochatzakis, and Natalia B. Perkins

Phys. Rev. B 110, 214406 (2024) - Published 4 December, 2024

This study explores the complex interplay of interactions in the classical Kitaev-Γ model, revealing a rich phase diagram characterized by a diverse range of magnetic ground states. It uncovers incommensurate spiral orders and chiral phases arising from the competition between Kitaev and Γ interactions, emphasizing the significant role of magnetic anisotropy. These findings provide valuable insights into the formation of unconventional magnetic order in systems with bond-anisotropic interactions, contributing to the understanding of experimental findings in 4d and 5d transition metal compounds with strong spin-orbit coupling.

Nonreciprocal transport of thermally generated magnons

M. Cosset-Chéneau, S. H. Tirion, X.-Y. Wei, J. Ben Youssef, and B. J. van Wees

Phys. Rev. B 110, 214418 (2024) - Published 11 December, 2024

The dynamic dipolar magnetic stray fields of magnons propagating in a magnetic insulator allow for a nonreciprocity of their transmission under a ferromagnetic gate. Such a nonreciprocity has been previously detected in conventional coherent magnon transport experiments. Here, the authors show that this mechanism can also lead to a nonreciprocity of thermally generated magnon transport, that is in a dependence of the nonlocal spin Seebeck effect amplitude on the thermal gradient direction.

Tensorial approach to altermagnetism

Paolo G. Radaelli

Phys. Rev. B 110, 214428 (2024) - Published 19 December, 2024

Seventy years after the first experimental observation of antiferromagnetism [Shull et al., Phys. Rev. 83, 333 (1951)], it was generally believed that all fundamental aspects of magnetism had been discovered. Much to everyone’s surprise, a new class of magnets emerged (named “altermagnets”), having antiferromagnetic spin arrangements but also strongly spin-polarized electronic bands – a property usually associated with ferromagnets. This paper analyses the symmetry conditions for the existence of momentum-space spin textures in antiferromagnets, and demonstrates that such textures generally contain a strong “altermagnetic” component, which can exist in the absence of spin-orbit coupling.

Nonreciprocal heat transport in the Kitaev chiral spin liquid

Yoshiki Sano, Daichi Takikawa, Masahiro O. Takahashi, Masahiko G. Yamada, Takeshi Mizushima, and Satoshi Fujimoto

Phys. Rev. B 110, 214430 (2024) - Published 20 December, 2024

Nonreciprocal transport, characterized by its direction-selective nature, holds significant potential for applications due to its rectification. Here, the authors theoretically investigate nonreciprocal heat transport in the Kitaev chiral spin liquid with open boundaries, where the Dzyaloshinskii-Moriya interaction is considered. They show the nonreciprocal heat transport even with considering the contributions from both of counter-propagating upper and lower edge states. Also, the potential exists to manipulate both of the directions and magnitude of the nonreciprocal current by varying external magnetic fields.

Effect of impurities and disorder on the braiding dynamics of Majorana zero modes

Cole Peeters, Themba Hodge, Eric Mascot, and Stephan Rachel

Phys. Rev. B 110, 214506 (2024) - Published 5 December, 2024

Majorana zero modes, the midgap states in topological superconductors, can be utilized as topological qubits in future quantum computers. By pairwise exchanging them (called braiding), quantum gates can be operated. Impurities and random disorder are usually foes of Majorana zero modes and braiding operations. The authors investigate here both the case of single impurities and random disorder on a T-junction geometry with four Majorana zero modes, and analyze the induced qubit errors. Surprisingly, there is a parameter regime in which disorder can even enhance the topological phase (black dots in the figure) and improve the braiding performance.

Anisotropic, multiband, and strong-coupling superconductivity of the Pb0.64Bi0.36 alloy

Sylwia Gutowska, Karolina Górnicka, Paweł Wójcik, Tomasz Klimczuk, and Bartlomiej Wiendlocha

Phys. Rev. B 110, 214510 (2024) - Published 13 December, 2024

Pb and Pb-Bi alloys are prototypes of strongly coupled superconductors, combining fascinating physics with application potential. Electron-phonon coupling (EPC) in cubic Pb is already strong, with λ1.5 and Tc=7.2 K. The work here demonstrates how alloying Pb with Bi — through electron doping, a cubic-to-hexagonal phase transition, and strong spin-orbit coupling — produces an alloy with record-strong EPC (λ2) and a higher Tc=8.6 K. Furthermore, the alloy’s anisotropic superconducting gap structure and strong electron scattering influence its thermodynamic properties, deviating from isotropic BCS and Eliashberg theories.

Superconductivity from repulsive interactions in Bernal-stacked bilayer graphene

Glenn Wagner, Yves H. Kwan, Nick Bultinck, Steven H. Simon, and S. A. Parameswaran

Phys. Rev. B 110, 214517 (2024) - Published 24 December, 2024

The authors propose here a simple three-pocket model for Kohn-Luttinger type interaction-driven superconductivity in untwisted “Bernal-stacked” bilayer graphene. The Cooper pairing results from overscreening of the purely repulsive Coulomb interaction, leading to p-wave superconductivity. The three-pocket model is substantiated by both random phase approximation and functional renormalization group calculations. These show that the proposed mechanism can account for the unusual behaviour seen in experiments, where superconductivity only emerges under application of an in-plane magnetic field or proximity-induced spin-orbit coupling.

Nanoscale structural correlations in a model cuprate superconductor

Zachary W. Anderson, Marin Spaić, Nikolaos Biniskos, Liam Thompson, Biqiong Yu, Jack Zwettler, Yaohua Liu, Feng Ye, Garrett E. Granroth, Matthew Krogstad, Raymond Osborn, Damjan Pelc, and Martin Greven

Phys. Rev. B 110, 214519 (2024) - Published 27 December, 2024

Nanoscale structural and electronic inhomogeneity is known to be common in the cuprate superconductors, and there is reason to believe that it is fundamental to much of the rich electronic phenomenology of these complex oxides. The authors use here advanced neutron and x-ray diffuse scattering to measure local structural correlations in HgBa2CuO4+δ, a high-symmetry cuprate with exemplary electronic properties. Combined diffuse scattering, spectral analysis, and structural modeling reveal locally correlated atomic displacements perpendicular to the CuO2 planes.

Effect of impurities and disorder on the braiding dynamics of Majorana zero modes

Phys. Rev. B 110, 214506 (2024) - Published 5 December, 2024

Majorana zero modes, the midgap states in topological superconductors, can be utilized as topological qubits in future quantum computers. By pairwise exchanging them (called braiding), quantum gates can be operated. Impurities and random disorder are usually foes of Majorana zero modes and braiding operations. The authors investigate here both the case of single impurities and random disorder on a T-junction geometry with four Majorana zero modes, and analyze the induced qubit errors. Surprisingly, there is a parameter regime in which disorder can even enhance the topological phase (black dots in the figure) and improve the braiding performance.

Pb and Pb-Bi alloys are prototypes of strongly coupled superconductors, combining fascinating physics with application potential. Electron-phonon coupling (EPC) in cubic Pb is already strong, with λ1.5 and Tc=7.2 K. The work here demonstrates how alloying Pb with Bi — through electron doping, a cubic-to-hexagonal phase transition, and strong spin-orbit coupling — produces an alloy with record-strong EPC (λ2) and a higher Tc=8.6 K. Furthermore, the alloy’s anisotropic superconducting gap structure and strong electron scattering influence its thermodynamic properties, deviating from isotropic BCS and Eliashberg theories.

Superconductivity from repulsive interactions in Bernal-stacked bilayer graphene

Phys. Rev. B 110, 214517 (2024) - Published 24 December, 2024

The authors propose here a simple three-pocket model for Kohn-Luttinger type interaction-driven superconductivity in untwisted “Bernal-stacked” bilayer graphene. The Cooper pairing results from overscreening of the purely repulsive Coulomb interaction, leading to p-wave superconductivity. The three-pocket model is substantiated by both random phase approximation and functional renormalization group calculations. These show that the proposed mechanism can account for the unusual behaviour seen in experiments, where superconductivity only emerges under application of an in-plane magnetic field or proximity-induced spin-orbit coupling.

Phys. Rev. B 110, 214519 (2024) - Published 27 December, 2024

Nanoscale structural and electronic inhomogeneity is known to be common in the cuprate superconductors, and there is reason to believe that it is fundamental to much of the rich electronic phenomenology of these complex oxides. The authors use here advanced neutron and x-ray diffuse scattering to measure local structural correlations in HgBa2CuO4+δ, a high-symmetry cuprate with exemplary electronic properties. Combined diffuse scattering, spectral analysis, and structural modeling reveal locally correlated atomic displacements perpendicular to the CuO2 planes.
