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 …

Recent theoretical and experimental progress on studying one-dimensional systems of
bosonic, fermionic, and Bose–Fermi mixtures of a few ultracold atoms confined in traps is …

Abstract The Yang–Baxter equation has long been recognised as the masterkey to
integrability, providing the basis for exactly solved models which capture the fundamental …

We present the complete phase diagram for one-dimensional binary mixtures of bosonic
ultracold atomic gases in a harmonic trap. We obtain exact results with direct numerical …

Neural networks have been proposed as efficient numerical wave function Ansätze, which
can be used to variationally search a wide range of functional forms for ground-state …

We study the dynamics of two strongly interacting bosons with an additional impurity atom
trapped in a harmonic potential. Using exact numerical diagonalization we are able to fully …

Cold atomic gases have provided us with a great number of opportunities for studying
various physical systems under controlled conditions that are seldom offered in other fields …

This is the first in a pair of articles that classify the configuration space and kinematic
symmetry groups for N identical particles in one-dimensional traps experiencing Galilean …

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 …

We study a three-body system with zero-range interactions in a one-dimensional harmonic
trap. The system consists of two spin-polarized fermions and a third particle which is distinct …
