Cold atomic gases have become a paradigmatic system for exploring fundamental physics,
which at the same time allows for applications in quantum technologies. The accelerating …

Following a “bottom-up approach” in understanding many-particle effects and dynamics we
provide a systematic ab initio study of the dependence of the breathing dynamics of ultracold …

We examine the problem of two particles confined in an isotropic harmonic trap, which
interact via a finite-range Gaussian-shaped potential in two spatial dimensions. We derive …

We study the emergence of Faraday waves in cigar-shaped collisionally inhomogeneous
Bose-Einstein condensates subject to periodic modulation of the radial confinement …

We analyze the dynamics of two atoms with a short‐ranged pair interaction in a one‐
dimensional harmonic trap with time‐dependent frequency. Our analysis is focused on two …

We study the tunneling dynamics in a time-periodically modulated two-mode Bose-Hubbard
model using Floquet theory. We consider situations where the system is in the self-trapping …

We investigate the breathing mode of harmonically trapped bosons in an optical lattice at
small site occupancies. The Bose-Hubbard model with a trapping potential is used to …

Faraday and resonant density waves emerge in Bose-Einstein condensates as a result of
harmonic driving of the system. They represent nonlinear excitations and are generated due …

We propose a new method, termed generator coordinate method (GCM)-correlated pair
wave function (CPWF), for studying one-dimensional bosons confined in harmonic …

A solvable model of a periodically driven trapped mixture of Bose–Einstein condensates,
consisting of N 1 interacting bosons of mass m 1 driven by a force of amplitude f L, 1 and N 2 …
