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 …

This article reviews theoretical and experimental developments for one-dimensional Fermi
gases. Specifically, the experimentally realized two-component delta-function interacting …

We study a system of two distinguishable fermions in a 1D harmonic potential. This system
has the exceptional property that there is an analytic solution for arbitrary values of the …

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 …

We study quasi-one-dimensional few-particle systems consisting of one to six ultracold
fermionic atoms in two different spin states with attractive interactions. We probe the system …

In one dimension, the study of magnetism dates back to the dawn of quantum mechanics
when Bethe solved the famous Heisenberg model that describes quantum behaviour in …

We show that strongly interacting multicomponent gases in one dimension realize an
effective spin chain, offering an alternative simple scenario for the study of one-dimensional …

We report on an implementation of the multiconfigurational time-dependent Hartree method
(MCTDH) for spin-polarized fermions (MCTDHF). Our approach is based on a map** for …

The nature of strongly interacting Fermi gases and magnetism is one of the most important
and studied topics in condensed-matter physics. Still, there are many open questions. A …

We investigate the formation of self-bound quantum droplets in a one-dimensional binary
mixture of bosonic atoms, applying the method of numerical diagonalization of the full …
