A fundamental assumption in statistical physics is that generic closed quantum many-body
systems thermalize under their own dynamics. Recently, the emergence of many-body …

Quasiperiodic systems offer an appealing intermediate between long-range ordered and
genuine disordered systems, with unusual critical properties. One-dimensional models that …

We employ ultracold atoms with controllable disorder and interaction to study the
paradigmatic problem of disordered bosons in the full disorder-interaction plane. Combining …

Disorder or quasidisorder is known to favor localization in many-body Bose systems. Here,
in contrast, we demonstrate an anomalous delocalization effect induced by …

We investigate the superfluid-insulator transition of one-dimensional interacting bosons in
both deep and shallow periodic potentials. We compare a theoretical analysis based on …

We uncover the exact athermal eigenstates in the Bose-Hubbard (BH) model with a three-
body constraint, motivated by the exact construction of quantum many-body scar (QMBS) …

The statistics of work done on a quantum system can be quantified by the two-point
measurement scheme. We show how the Shannon entropy of the work distribution admits a …

We consider weakly interacting bosons in a 1D quasiperiodic potential (Aubry-Azbel-Harper
model) in the regime where all single-particle states are localized. We show that the …

We study the localization of collective pair excitations in weakly interacting Bose superfluids
in one-dimensional quasiperiodic lattices. The localization diagram is first determined …

Motivated by recent optical lattice experiments [J.-y. Choi, Science 352, 1547 (2016)
SCIEAS 0036-8075 10.1126/science. aaf8834], we study the dynamics of strongly …
