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 …

The occupation of more than one single-particle state, and hence the emergence of
fragmentation, is a many-body phenomenon occurring for systems of spatially confined …

The beyond mean-field (MF) dynamics of a bent dark soliton (BDS) embedded in a two-
dimensional repulsively interacting Bose–Einstein condensate is explored. We examine the …

The theoretical investigation of rotating Bose–Einstein condensates has mainly focused on
the emergence of quantum vortex states and the condensed properties of such systems. In …

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 …

In this work, we study the out-of-equilibrium many-body tunneling dynamics of a Bose-
Einstein condensate in a two-dimensional radial double well. We investigate the impact of …

We provide accurate expressions for the s-wave scattering length for a Gaussian potential
well in one, two, and three spatial dimensions. The Gaussian potential is widely used as a …

We consider a small number of identical bosons trapped in a two-dimensional isotropic
harmonic potential and also the N-boson system when it is feasible. The atom-atom …

A hyperbolic singularity in the wave function of s-wave interacting atoms is the root problem
for any accurate numerical simulation. Here, we apply the transcorrelated method, whereby …

A two-dimensional Bose-Einstein condensate (BEC) split by a radial potential barrier is
investigated. We determine on an accurate many-body level the system's ground-state …
