Quantum computers, though not yet available on the market, will revolutionize the future of
information processing. Quantum computers for special purposes like quantum simulators …

The main theme of this review is the many-body physics of vortices in quantum droplets of
bosons or fermions in the limit of small particle numbers. Systems of interest include cold …

Nonequilibrium phase transitions exist in damped-driven open quantum systems when the
continuous tuning of an external parameter leads to a transition between two robust steady …

The quantum phase transition of the Dicke model has been observed recently in a system
formed by motional excitations of a laser-driven Bose-Einstein condensate coupled to an …

Single experimental shots of ultracold quantum gases sample the many-particle probability
distribution. In a few cases such single shots could be successfully simulated from a given …

We consider a Bose-Einstein condensate in a double-well potential undergoing a dynamical
transition from the regime of Josephson oscillations to the regime of self-trapping. We …

The decay of a vortex from a nonrotating high temperature Bose-Einstein condensate is
modeled using the stochastic projected Gross-Pitaevskii equation (SPGPE). In order to …

We study theoretically the ground states of two-dimensional Bose-Hubbard models which
are frustrated by gauge fields. Motivated by recent proposals for the implementation of …

Vortices are essential to angular momentum in quantum systems such as ultracold atomic
gases. The existence of quantized vorticity in bosonic systems stimulated the development …

We present exact expressions for the quantum sloshing of Bose-Einstein condensates in a
tilted two-well potential. Tunneling is suppressed by a small potential difference between …
