observation of fine aspects of closed quantum many-body systems, as either the regime …

Subdiffusion and heat transport in a tilted two-dimensional Fermi-Hubbard system

E Guardado-Sanchez, A Morningstar, BM Spar… - Physical Review X, 2020 - APS
Using quantum gas microscopy, we study the late-time effective hydrodynamics of an

Bloch oscillations in the absence of a lattice

F Meinert, M Knap, E Kirilov, K Jag-Lauber… - Science, 2017 - science.org
The interplay of strong quantum correlations and far-from-equilibrium conditions can give
rise to striking dynamical phenomena. We experimentally investigated the quantum motion …

Chaos and ergodicity across the energy spectrum of interacting bosons

L Pausch, EG Carnio, A Rodríguez, A Buchleitner - Physical Review Letters, 2021 - APS
We identify the chaotic phase of the Bose-Hubbard Hamiltonian by the energy-resolved
correlation between spectral features and structural changes of the associated eigenstates …

Classical synchronization indicates persistent entanglement in isolated quantum systems

D Witthaut, S Wimberger, R Burioni, M Timme - Nature communications, 2017 - nature.com

Quantum quench in the sine-Gordon model

B Bertini, D Schuricht, FHL Essler - Journal of Statistical …, 2014 - iopscience.iop.org
We consider the time evolution in the repulsive sine-Gordon quantum field theory after the

Glimmers of a quantum KAM theorem: insights from quantum quenches in one-dimensional Bose gases

GP Brandino, JS Caux, RM Konik - Physical Review X, 2015 - APS
Real-time dynamics in a quantum many-body system are inherently complicated and hence
difficult to predict. There are, however, a special set of systems where these dynamics are …

Observation and uses of position-space Bloch oscillations in an ultracold gas
