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 …

Understanding the effect of correlations in interacting many-body systems is one of the main
challenges in quantum mechanics. While the general problem can only be addressed by …

A system of two species of fermions of different mass confined in a one-dimensional
harmonic trap is studied with an exact diagonalization approach. It is shown that a mass …

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 …

Strongly interacting particles in one dimension subject to external confinement have become
a topic of considerable interest due to recent experimental advances and the development …

We apply the framework of non-equilibrium quantum thermodynamics to the physics of
quenched small-sized bosonic quantum gases in a one-dimensional harmonic trap. We …

We present a numerical analysis of spin-$\tfrac {1}{2} $ fermions in a one-dimensional
harmonic potential in the presence of a magnetic point-like impurity at the center of the trap …

The ground-state properties of a few spin-1/2 fermions with different masses and interacting
via short-range contact forces are studied within an exact diagonalization approach. It is …
