Nonequilibrium non-Markovian steady states in open quantum many-body systems: Persistent oscillations in Heisenberg quantum spin chains

R Finsterhölzl, M Katzer, A Carmele - Physical Review B, 2020 - APS
We investigate the effect of a non-Markovian, structured reservoir on an open Heisenberg
spin chain. We establish a coherent self-feedback mechanism as the reservoir couples …

Form factor bootstrap in the thermally perturbed tricritical Ising model

B Fitos, G Takács - Physical Review D, 2024 - APS
We derive a systematic construction for form factors of relevant fields in the thermal

Phase Diagram of Abelian-Higgs Model and Its Critical Point

T Chanda, M Lewenstein, J Zakrzewski… - Physical Review Letters, 2022 - APS
We determine the phase diagram of the Abelian-Higgs model in one spatial dimension and
time (1+ 1 D) on a lattice. We identify a line of first order phase transitions separating the …
