Non-Hermitian Floquet topological matter—a review

L Zhou, DJ Zhang - Entropy, 2023 - mdpi.com
The past few years have witnessed a surge of interest in non-Hermitian Floquet topological
matter due to its exotic properties resulting from the interplay between driving fields and non …

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 …

Quantum entanglement and non-Hermiticity in free-fermion systems

LM Chen, Y Zhou, SA Chen, P Ye - Chinese Physics Letters, 2024 - iopscience.iop.org
This topical review article reports rapid progress on the generalization and application of

Liouvillian skin effect in a one-dimensional open many-body quantum system with generalized boundary conditions

L Mao, X Yang, MJ Tao, H Hu, L Pan - Physical Review B, 2024 - APS
The non-Hermitian skin effect, in which eigenstates of non-Hermitian Hamiltonians are
localized at one boundary in the open boundary condition, has attracted great interest …

Edge and corner skin effects of chirally coupled magnons characterized by a topological winding tuple

C Cai, DM Kennes, MA Sentef, T Yu - Physical Review B, 2023 - APS
We investigate a long-ranged coupled and non-Hermitian two-dimensional array of
nanomagnets, fabricated on a thin magnetic substrate and subjected to an in-plane …

Correlation versus dissipation in a non-Hermitian Anderson impurity model

K Yamamoto, M Nakagawa, N Kawakami - arXiv preprint arXiv …, 2024 - arxiv.org
We analyze the competition between strong correlations and dissipation in quantum impurity
systems from the Kondo regime to the valence fluctuation regime by developing a slave …

Phase diagram of non-Hermitian BCS superfluids in a dissipative asymmetric Hubbard model

S Takemori, K Yamamoto, A Koga - Physical Review B, 2024 - APS
We investigate the non-Hermitian (NH) attractive Fermi-Hubbard model with asymmetric
hopping and complex-valued interactions, which can be realized by collective one-body loss …

Breakdown of linear spin-wave theory in a non-Hermitian quantum spin chain

J Despres, L Mazza, M Schirò - Physical Review B, 2024 - APS
We present the spin-wave theory of the excitation spectrum and quench dynamics of the non-
Hermitian transverse-field Ising model. The complex excitation spectrum is obtained for a …

L Rødland, C Ortega-Taberner, M Agarwal… - Physical Review B, 2024 - APS
We study the effect of disorder on Z 2 quantum spin liquids with a Majorana Fermi line
(respectively a surface in three dimensions), and we show that depending on the …

Work statistics and generalized Loschmidt echo for the Hatano-Nelson model

B Dóra, CP Moca - Physical Review B, 2024 - APS
We focus on the biorthogonal work statistics of the interacting many-body Hatano-Nelson
model after switching on the imaginary vector potential. We introduce a generalized …
