Non-Hermitian pseudomodes for strongly coupled open quantum systems: Unravelings, correlations, and thermodynamics

P Menczel, K Funo, M Cirio, N Lambert, F Nori - Physical Review Research, 2024 - APS
The pseudomode framework provides an exact description of the dynamics of an open
quantum system coupled to a non-Markovian environment. Using this framework, the …

Local quantum channels giving rise to quasi-local Gibbs states

I Arad, R Firanko, O Gurevich - arxiv preprint arxiv:2408.08672, 2024 - arxiv.org
We study the steady-state properties of quantum channels with local Kraus operators. We
consider a large family that consists of general ergodic 1-local (non-interacting) terms and …
