Geometric properties of adiabatic quantum thermal machines

Bibek Bhandari, Pablo Terrén Alonso, Fabio Taddei, Felix von Oppen, Rosario Fazio, and Liliana Arrachea

Phys. Rev. B 102, 155407 (2020) - Published 8 October, 2020

A quantum thermal machine can be controlled by time-periodic perturbations that define a cycle, as in conventional macroscopic thermal machines. This paper presents a general and unified approach to the study of quantum thermal machines, including both heat engines and refrigerators, which operate under periodic adiabatic driving and are in contact with thermal reservoirs kept at different temperatures. Importantly, many observables characterizing the operation and the performance of these machines are geometric in nature.

Dirac fermions in antiferromagnetic FeSn kagome lattices with combined space inversion and time-reversal symmetry

Zhiyong Lin, Chongze Wang, Pengdong Wang, Seho Yi, Lin Li, Qiang Zhang, Yifan Wang, Zhongyi Wang, Hao Huang, Yan Sun, Yaobo Huang, Dawei Shen, Donglai Feng, Zhe Sun, Jun-Hyung Cho, Changgan Zeng, and Zhenyu Zhang

Phys. Rev. B 102, 155103 (2020) - Published 2 October, 2020

The authors demonstrate experimentally the existence of theoretically predicted antiferromagnetic Dirac states in the kagome compound FeSn, where the P and T symmetries are individually broken but the combined PT symmetry is present. Moreover, their theoretical analysis reveals that, due to the salient antiferromagnetic structure, the Dirac fermions can be transformed into either massless/massive Weyl or massive Dirac fermions via symmetry manipulation, and the study does report the experimental observation of Weyl-like cones at the surface driven by PT symmetry breaking that is induced by the Stark effect.

High magnetic field spin-valley-split Shubnikov–de Haas oscillations in a WSe2 monolayer

Banan Kerdi, Mathieu Pierre, Robin Cours, Bénédicte Warot-Fonrose, Michel Goiran, and Walter Escoffier

Phys. Rev. B 102, 155106 (2020) - Published 6 October, 2020

Here, the resistance of a WSe2 monolayer is measured under a strong, pulsed magnetic field. Non-1B-periodic Shubnikov–de Haas oscillations are observed and attributed to a large spin-valley splitting of the valence band. The authors develop a model to simulate the magnetoresistancein the regime of partially resolved Zeeman splitting of the Landau levels. The ratio between the Zeeman and cyclotron energies, obtained from the fit of the oscillations, translates into a density-dependent, large-hole Landé factor.

Optically induced flat bands in twisted bilayer graphene

Or Katz, Gil Refael, and Netanel H. Lindner

Phys. Rev. B 102, 155123 (2020) - Published 16 October, 2020

Twisted bilayer graphene exhibits strong electronic correlations at the “magic angle” – a special angle of the twist, at which isolated flat bands emerge in the material’s band structure. The authors present here a new mechanism to induce isolated flat bands at angles below the magic angle using visible/infrared light. This mechanism enables optical control of the flatness, spectral isolation, and topological properties of the bands, using frequencies which are well below the material’s bandwidth. Floquet engineering using optical fields and moiré superlattices may therefore play an important role in the exploration of on-demand nonequilibrium quantum phases of matter.

Changes of Fermi surface topology due to the rhombohedral distortion in SnTe

Christopher D. O'Neill, Oliver J. Clark, Harry D. J. Keen, Federico Mazzola, Igor Marković, Dmitry A. Sokolov, Andreas Malekos, Phil D. C. King, Andreas Hermann, and Andrew D. Huxley

Phys. Rev. B 102, 155132 (2020) - Published 21 October, 2020

Cubic SnTe is known to undergo a rhombohedral structural distortion on cooling. Here, the authors show via measuring quantum oscillations that the distortion has a significant impact on the Fermi surface topology. In the distorted structure, several neighboring oscillation frequencies exist as a result of the rhombohedral symmetry breaking and of the spin-orbit splitting, lifting the band degeneracy. By applying a pressure of 10 kbars, it is found that the oscillation spectrum changes and the distortion is suppressed. This allows the authors to determine the contribution to the Hall effect for each feature of the Fermi surface. Additionally, they find unusual linear magnetoresistance that they attribute to regions of the Fermi surface with high curvature.

Dirac quantum well engineering on the surface of a topological insulator

X. Lu and M. O. Goerbig

Phys. Rev. B 102, 155311 (2020) - Published 26 October, 2020

Making topological insulators into thin films is a promising way to rule out the undesirable bulk contribution for applications, but one then needs to worry about coupling between surface states at opposite sides of the film. The understanding of this coupling is addressed here. The coupling and the resulting gap opening in the chiral states (n=0) turn out to be qualitatively different and quantitatively much smaller compared to those in massive Volkov-Pankratov surface states (n>0), which are not protected by chirality.

Quantifying nonequilibrium thermodynamic operations in a multiterminal mesoscopic system

Fatemeh Hajiloo, Rafael Sánchez, Robert S. Whitney, and Janine Splettstoesser

Phys. Rev. B 102, 155405 (2020) - Published 6 October, 2020

This theoretical work studies a nanoscale machine that converts a nonequilibrium distribution (e.g., a mixture of hot and cold electrons) into useful work, with an efficiency that “appears” to exceed the Carnot efficiency. This is called an N-demon (”N” for nonequilibrium) in analogy with a Maxwell demon. The authors show here that the laws of thermodynamics are not violated because the machine consumes the free energy of the nonequilibrium distribution. Why not use such machines to exploit the nonequilibrium distributions that are the “waste” output of other nanoscale device operations?

Viscous Maxwell-Chern-Simons theory for topological electromagnetic phases of matter

Todd Van Mechelen and Zubin Jacob

Phys. Rev. B 102, 155425 (2020) - Published 26 October, 2020

Chern-Simons theories, initially developed for high-energy physics, have been very successful in explaining integer and fractional quantum Hall phases of matter, topological insulators, and Weyl semimetals. However, it was an open question as to whether Chern-Simons theories can be adapted to topological photonics. Here, the authors develop a viscous Maxwell-Chern-Simons theory to capture the fundamental physics of a topological electromagnetic phase of matter. The theory applies to viscous Hall fluids and predicts the existence of unique spin-1 photonic skyrmions in momentum space.

Making topological insulators into thin films is a promising way to rule out the undesirable bulk contribution for applications, but one then needs to worry about coupling between surface states at opposite sides of the film. The understanding of this coupling is addressed here. The coupling and the resulting gap opening in the chiral states (n=0) turn out to be qualitatively different and quantitatively much smaller compared to those in massive Volkov-Pankratov surface states (n>0), which are not protected by chirality.

This theoretical work studies a nanoscale machine that converts a nonequilibrium distribution (e.g., a mixture of hot and cold electrons) into useful work, with an efficiency that “appears” to exceed the Carnot efficiency. This is called an N-demon (”N” for nonequilibrium) in analogy with a Maxwell demon. The authors show here that the laws of thermodynamics are not violated because the machine consumes the free energy of the nonequilibrium distribution. Why not use such machines to exploit the nonequilibrium distributions that are the “waste” output of other nanoscale device operations?

A quantum thermal machine can be controlled by time-periodic perturbations that define a cycle, as in conventional macroscopic thermal machines. This paper presents a general and unified approach to the study of quantum thermal machines, including both heat engines and refrigerators, which operate under periodic adiabatic driving and are in contact with thermal reservoirs kept at different temperatures. Importantly, many observables characterizing the operation and the performance of these machines are geometric in nature.

Viscous Maxwell-Chern-Simons theory for topological electromagnetic phases of matter

Todd Van Mechelen and Zubin Jacob

Phys. Rev. B 102, 155425 (2020) - Published 26 October, 2020

Chern-Simons theories, initially developed for high-energy physics, have been very successful in explaining integer and fractional quantum Hall phases of matter, topological insulators, and Weyl semimetals. However, it was an open question as to whether Chern-Simons theories can be adapted to topological photonics. Here, the authors develop a viscous Maxwell-Chern-Simons theory to capture the fundamental physics of a topological electromagnetic phase of matter. The theory applies to viscous Hall fluids and predicts the existence of unique spin-1 photonic skyrmions in momentum space.
