Skin modes in a nonlinear Hatano-Nelson model

B Many Manda, R Carretero-González, PG Kevrekidis… - Physical Review B, 2024 - APS
Non-Hermitian lattices with nonreciprocal couplings under open boundary conditions are
known to possess linear modes exponentially localized on one edge of the chain. This …

Exceptional points and exponential sensitivity for periodically driven Lindblad equations

J Larson, S Qvarfort - Open Systems & Information Dynamics, 2023 - World Scientific
In this contribution to the memorial issue of Göran Lindblad, we investigate the periodically
driven Lindblad equation for a two-level system. We analyze the system using both adiabatic …

Non-Hermitian Haldane-Hubbard model: Effective description of one-and two-body dissipation

C Wang, TC Yi, J Li, R Mondaini - Physical Review B, 2023 - APS
Using numerically exact diagonalization, we study the correlated Haldane-Hubbard model
in the presence of dissipation. Such dissipation can be modeled at short times by the …

Exploring the impact of fluctuation-induced criticality on non-Hermitian skin effect and quantum sensors

C Ehrhardt, J Larson - Physical Review Research, 2024 - APS
In this paper we present a concrete example comparing the results predicted by non-
Hermitian quantum mechanics with those of a more comprehensive description that …
