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 …

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 …

We study two-component atomic gas mixtures in one dimension involving both bosons and
fermions. When the interspecies interaction is attractive, we report a rich variety of coherent …

We study one-dimensional (1D) strongly interacting Bose–Fermi mixtures by both the exact
Bethe-ansatz method and variational perturbation theory within the degenerate ground state …

We investigate universal properties of one-dimensional multicomponent systems composed
of fermions, bosons, or an arbitrary mixture, with contact interactions and subjected to an …

We address the problem of computing the thermodynamic properties of the repulsive one-
dimensional two-component Fermi gas with contact interaction, also known as the Gaudin …

The relative motion of three impenetrable particles on a ring, in our case two identical
fermions and one impurity, is isomorphic to a triangular quantum billiard. Depending on the …

We make use of a simple pair correlated wave function approach to obtain results for the
ground-state densities and momentum distribution of a one-dimensional three-body bosonic …
