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 …

Multicomponent quantum mixtures in one dimension can be characterized by their symmetry
under particle exchange. For a strongly interacting Bose-Bose mixture, we show that the …

In low-dimensional systems, indistinguishable particles can display statistics that interpolate
between bosons and fermions. Signatures of these “anyons” have been detected in two …

We derive a systematic approach to the thermodynamics of quantum systems based on the
underlying symmetry groups. We first show that the entropy of a system can be described in …

After release from the trap the momentum distribution of an impenetrable gas asymptotically
approaches that of a spinless noninteracting Fermi gas in the initial trap. This phenomenon …

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 study Tan's contact of a one-dimensional quantum gas of N repulsive identical bosons
confined in a harmonic trap at finite temperature. This canonical ensemble framework …

One of quantum physics' fundamental, but largely unsolved, problems is the computation of
the correlation functions in many-body systems. We address this problem in the case of one …
