Skin modes in a nonlinear Hatano-Nelson model
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
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
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 …
