Non-Hermitian Fermi-Dirac distribution in persistent current transport

PX Shen, Z Lu, JL Lado, M Trif - Physical Review Letters, 2024 - APS
Persistent currents circulate continuously without requiring external power sources. Here,
we extend their theory to include dissipation within the framework of non-Hermitian quantum …

Dual topological characterization of non-Hermitian Floquet phases

L Zhou, Y Gu, J Gong - Physical Review B, 2021 - APS
Non-Hermiticity is expected to add far more physical features to the already rich Floquet
topological phases of matter. Nevertheless, a systematic approach to characterize non …

Non-Hermitian pseudo-gaps

L Li, CH Lee - Science Bulletin, 2022 - Elsevier
The notion of a band gap is ubiquitous in the characterization of matter. Particularly
interesting are pseudo-gaps, which are enigmatic regions of very low density of states that …

Floquet engineering of Kitaev quantum magnets

U Kumar, S Banerjee, SZ Lin - Communications Physics, 2022 - nature.com
In recent years, there has been an intense search for materials realizing the Kitaev quantum
spin liquid model. A number of edge-shared compounds with strong spin-orbit coupling …

Topological characterization and stability of Floquet Majorana modes in Rashba nanowires

D Mondal, AK Ghosh, T Nag, A Saha - Physical Review B, 2023 - APS
We theoretically investigate a practically realizable Floquet topological superconductor
model based on a one-dimensional Rashba nanowire and proximity-induced s-wave …

Bulk-boundary correspondence in disordered non-Hermitian systems

ZQ Zhang, H Liu, H Liu, H Jiang, XC Xie - Science Bulletin, 2023 - Elsevier
The bulk-boundary correspondence (BBC) refers to the consistency between eigenvalues
calculated under open and periodic boundary conditions. This consistency can be destroyed …

Square-root Floquet topological phases and time crystals

RW Bomantara - Physical Review B, 2022 - APS
Periodically driven (Floquet) phases are attractive due to their ability to host unique physical
phenomena with no static counterparts. We propose a general approach in nontrivially …

Noncollinear twisted RKKY interaction on the optically driven SnTe (001) surface

M Yarmohammadi, M Bukov, MH Kolodrubetz - Physical Review B, 2023 - APS
The nontrivial spin texture on the (001) surface of topological crystalline insulator SnTe hosts
exotic scientific importance and spintronic applications. Here, we study the effects of weak …

Floquet engineering of many-body states by the ponderomotive potential

Z Sun - Physical Review B, 2024 - APS
The ponderomotive force is an effective static force that a particle feels in an oscillating field,
whose static potential may be called the ponderomotive potential. We generalize this notion …

Single and multifrequency driving protocols in a Rashba nanowire proximitized to an -wave superconductor

K Roy, S Basu - Physical Review B, 2024 - APS
We perform systematic analyses of single and multifrequency driving protocols on a Rashba
nanowire with superconducting correlations induced by proximity effects. The results for the …
