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 …

One-dimensional spinor gases with strong δ interaction fermionize and form a spin chain.
The spatial degrees of freedom of this atom chain can be described by a mapping to …

Strongly interacting one-dimensional (1D) Bose–Fermi mixtures form a tunable XXZ spin
chain. Within the spin-chain model developed here, all properties of these systems can be …

The exotic phenomenon of time-translation-symmetry breaking under periodic driving—one
of the main features of the so-called time crystals—has been shown to occur in many-body …

We have developed an efficient computational method to treat long, one-dimensional
systems of strongly interacting atoms forming self-assembled spin chains. Such systems can …

The decoupling of spin and density dynamics is a remarkable feature of quantum one-
dimensional many-body systems. In a few-body regime, however, little is known about this …

A generalized effective spin-chain model is developed for studies of strongly interacting
spinor gases in a one-dimensional (1D) optical lattice. The spinor gas is mapped to a system …

In this paper we study a mixed system of bosons and fermions with up to six particles in total.
All particles are assumed to have the same mass. The two-body interactions are repulsive …
