Operator growth and Krylov construction in dissipative open quantum systems

A Bhattacharya, P Nandy, PP Nath, H Sahu - Journal of High Energy …, 2022 - Springer
A bstract Inspired by the universal operator growth hypothesis, we extend the formalism of
Krylov construction in dissipative open quantum systems connected to a Markovian bath …

Entanglement transition from variable-strength weak measurements

M Szyniszewski, A Romito, H Schomerus - Physical Review B, 2019 - APS
We show that weak measurements can induce a quantum phase transition of interacting
many-body systems from an ergodic thermal phase with a large entropy to a nonergodic …

Universal spectra of random Lindblad operators

S Denisov, T Laptyeva, W Tarnowski, D Chruściński… - Physical review …, 2019 - APS
To understand the typical dynamics of an open quantum system in continuous time, we
introduce an ensemble of random Lindblad operators, which generate completely positive …

Spectral properties of disordered interacting non-Hermitian systems

S Ghosh, S Gupta, M Kulkarni - Physical Review B, 2022 - APS
Non-Hermitian systems have gained a lot of interest in recent years. However, notions of
chaos and localization in such systems have not reached the same level of maturity as in the …

Dissipation-induced extended-localized transition

Y Liu, Z Wang, C Yang, J Jie, Y Wang - Physical Review Letters, 2024 - APS
A mobility edge (ME), representing the critical energy that distinguishes between extended
and localized states, is a key concept in understanding the transition between extended …

Entanglement dynamics of a many-body localized system coupled to a bath

E Wybo, M Knap, F Pollmann - Physical Review B, 2020 - APS
The combination of strong disorder and interactions in closed quantum systems can lead to
many-body localization (MBL). However, this quantum phase is not stable when the system …

Quantum jumps in driven-dissipative disordered many-body systems

S Gupta, HK Yadalam, M Kulkarni, C Aron - Physical Review A, 2024 - APS
We discuss how quantum jumps affect localized regimes in driven-dissipative disordered
many-body systems featuring a localization transition. We introduce a deformation of the …

Dissipation induced ergodic-nonergodic transitions in finite-height mosaic Wannier-Stark lattices

XP Jiang, X Yang, Y Hu, L Pan - arxiv preprint arxiv:2407.17301, 2024 - arxiv.org
Recent research has observed the occurrence of pseudo-mobility edge (ME) within a
modulated mosaic model incorporating the Wannier-Stark potential. This pseudo-ME, which …

Many-body open quantum systems beyond Lindblad master equations

X Xu, J Thingna, C Guo, D Poletti - Physical Review A, 2019 - APS
Many-body quantum systems present a rich phenomenology which can be significantly
altered when they are in contact with an environment. In order to study such setups, a …

Lindbladian many-body localization

R Hamazaki, M Nakagawa, T Haga, M Ueda - arxiv preprint arxiv …, 2022 - arxiv.org
We discover a novel localization transition that alters the dynamics of coherence in
disordered many-body spin systems subject to Markovian dissipation. The transition occurs …
