Hilbert space fragmentation and slow dynamics in particle-conserving quantum East models

P Brighi, M Ljubotina, M Serbyn - SciPost Physics, 2023 - scipost.org
Quantum kinetically constrained models have recently attracted significant attention due to
their anomalous dynamics and thermalization. In this work, we introduce a hitherto …

Validity of mean-field theory in a dissipative critical system: Liouvillian gap, -symmetric antigap, and permutational symmetry in the model

D Huybrechts, F Minganti, F Nori, M Wouters… - Physical Review B, 2020 - APS
We study the all-to-all connected XYZ (anisotropic-Heisenberg) spin model with local and
collective dissipations, comparing the results of mean-field (MF) theory with the solution of …

Reaction-limited quantum reaction-diffusion dynamics

G Perfetto, F Carollo, JP Garrahan, I Lesanovsky - Physical Review Letters, 2023 - APS
We consider the quantum nonequilibrium dynamics of systems where fermionic particles
coherently hop on a one-dimensional lattice and are subject to dissipative processes …

Absorbing state phase transition with competing quantum and classical fluctuations

M Marcuzzi, M Buchhold, S Diehl, I Lesanovsky - Physical review letters, 2016 - APS
Stochastic processes with absorbing states feature examples of nonequilibrium universal
phenomena. While the classical regime has been thoroughly investigated in the past …

Kinetically constrained models constructed from dissipative quantum dynamics

S Maity, R Hamazaki - Physical Review B, 2024 - APS
We propose a construction of kinetically constrained models using the Markovian quantum
dynamics under strong dissipation. Engineering the Gorini-Kossakowski-Sudarshan …

Theory of classical metastability in open quantum systems

K Macieszczak, DC Rose, I Lesanovsky… - Physical Review …, 2021 - APS
We present a general theory of classical metastability in open quantum systems.
Metastability is a consequence of a large separation in timescales in the dynamics, leading …

Two-time correlations probing the dynamics of dissipative many-body quantum systems: Aging and fast relaxation

B Sciolla, D Poletti, C Kollath - Physical Review Letters, 2015 - APS
We use two-time correlation functions to study the complex dynamics of dissipative many-
body quantum systems. In order to measure, understand, and categorize these correlations …

Quantum reaction-limited reaction-diffusion dynamics of annihilation processes

G Perfetto, F Carollo, JP Garrahan, I Lesanovsky - Physical Review E, 2023 - APS
We investigate the quantum reaction-diffusion dynamics of fermionic particles which
coherently hop in a one-dimensional lattice and undergo annihilation reactions. The latter …
