Universality in driven open quantum matter

LM Sieberer, M Buchhold, J Marino, S Diehl - arXiv preprint arXiv …, 2023 - arxiv.org
Universality is a powerful concept, which enables making qualitative and quantitative
predictions in systems with extensively many degrees of freedom. It finds realizations in …

Entanglement measures in a nonequilibrium steady state: Exact results in one dimension

S Fraenkel, M Goldstein - SciPost Physics, 2021 - scipost.org
Entanglement plays a prominent role in the study of condensed matter many-body systems:
Entanglement measures not only quantify the possible use of these systems in quantum …

Role of coherence in the nonequilibrium thermodynamics of quantum systems

G Francica, J Goold, F Plastina - Physical Review E, 2019 - APS
Exploiting the relative entropy of coherence, we isolate the coherent contribution in the
energetics of a driven nonequilibrium quantum system. We prove that a division of the …

Integrable floquet dynamics

V Gritsev, A Polkovnikov - SciPost Physics, 2017 - scipost.org
We discuss several classes of integrable Floquet systems, ie systems which do not exhibit
chaotic behavior even under a time dependent perturbation. The first class is associated …

Onset of Floquet thermalization

A Haldar, R Moessner, A Das - Physical Review B, 2018 - APS
In the presence of interactions, a closed, homogeneous (disorder-free) many-body system is
believed to generically heat up to an “infinite temperature” ensemble when subjected to a …

Driving enhanced quantum sensing in partially accessible many-body systems

U Mishra, A Bayat - Physical Review Letters, 2021 - APS
The ground-state criticality of many-body systems is a resource for quantum-enhanced
sensing, namely, the Heisenberg precision limit, provided that one has access to the whole …

Dynamics of inhomogeneous spin ensembles with all-to-all interactions: Breaking permutational invariance

F Iemini, D Chang, J Marino - Physical Review A, 2024 - APS
We investigate the consequences of introducing nonuniform initial conditions in the
dynamics of spin ensembles characterized by all-to-all interactions. Specifically, our study …

Floquet engineering in quantum chains

DM Kennes, A De La Torre, A Ron, D Hsieh, AJ Millis - Physical Review Letters, 2018 - APS
We consider a one-dimensional interacting spinless fermion model, which displays the well-
known Luttinger liquid (LL) to charge density wave (CDW) transition as a function of the ratio …

Exact solution of time-dependent Lindblad equations with closed algebras
