Dynamical Topological Transitions in the Massive Schwinger Model with a Term

TV Zache, N Mueller, JT Schneider, F Jendrzejewski… - Physical review …, 2019 - APS
Aiming at a better understanding of anomalous and topological effects in gauge theories out
of equilibrium, we study the real-time dynamics of a prototype model for CP violation, the …

From non-Hermitian linear response to dynamical correlations and fluctuation-dissipation relations in quantum many-body systems

KT Geier, P Hauke - PRX Quantum, 2022 - APS
Quantum many-body systems are characterized by their correlations. While equal-time
correlators and unequal-time commutators between operators are standard observables, the …

Probing eigenstate thermalization in quantum simulators via fluctuation-dissipation relations

A Schuckert, M Knap - Physical Review Research, 2020 - APS
The eigenstate thermalization hypothesis (ETH) offers a universal mechanism for the
approach to equilibrium of closed quantum many-body systems. So far, however …

Unraveling the nature of universal dynamics in theories

K Boguslavski, A Piñeiro Orioli - Physical Review D, 2020 - APS
Many-body quantum systems far from equilibrium can exhibit universal scaling dynamics
which defy standard classification schemes. Here, we disentangle the dominant excitations …

Optical spin conductivity in ultracold quantum gases

Y Sekino, H Tajima, S Uchino - Physical Review Research, 2022 - APS
We show that the optical spin conductivity, which is a small ac response of a bulk spin
current and elusive in condensed matter systems, can be measured in ultracold atoms. We …

Many-body interferometry of one-dimensional integrable systems

M Arzamasovs, M Liu, Y Zhang, R Tian, Z Li… - arXiv preprint arXiv …, 2024 - arxiv.org
We propose using many-body Ramsey interferometry to measure non-equilibrium
correlation functions of one-dimensional (1D) integrable systems. The 1D transverse-field …

Probing Dynamics and Correlations in Cold-Atom Quantum Simulators

KT Geier - 2022 - iris.unitn.it
I simulatori quantistici ad atomi freddi offrono possibilità uniche per preparare, manipolare e
sondare sistemi quantistici a molti corpi. Tuttavia, nonostante l'alto livello di controllo …

Universal dynamics and thermalization in isolated quantum systems

L Shen - 2020 - archiv.ub.uni-heidelberg.de
The goal of this work is to explore the relaxation dynamics of isolated quantum systems
driven out of equilibrium, focusing on nonequilibrium phenomena emerging on the way to …

Probing nonequilibrium quantum matter with two-time correlation functions

A Schuckert - 2021 - mediatum.ub.tum.de
We study the thermalization dynamics of many-body quantum systems, ranging from many-
body chaos close to a phase transition over eigenstate thermalization in quantum simulators …

Ancilla-assisted probing of temporal quantum correlations of large spins

M Kastner - Physical Review A, 2020 - APS
When measuring quantum spins at two or more different times, the later measurements are
affected by measurement backaction occurring due to the earlier measurements. This makes …
