We study the nonequilibrium dynamics of a Tonks-Girardeau gas released from a parabolic
trap to a circle. We present the exact analytic solution of the many body dynamics and prove …

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 …

In one-dimensional (1D) quantum gases, the momentum distribution (MD) of the atoms is a
standard experimental observable, routinely measured in various experimental setups. The …

In quantum gases with contact repulsion, the distribution of momenta of the atoms typically
decays as∼ 1/| p| 4 at large momentum p. Tan's relation connects the amplitude of that 1/| p …

We study persistent currents for interacting one-dimensional bosons on a tight ring trap,
subjected to a rotating barrier potential, which induces an artificial U (1) gauge field. We …

We show that a quantum Otto cycle in which the medium, an interacting ultracold gas, is
driven between a superfluid and an insulating phase can outperform similar single particle …

A gas of interacting fermions confined in a quasi one-dimensional geometry shows a BEC to
BCS crossover upon slowly driving its coupling constant through a confinement-induced …

We consider the non-equilibrium dynamics of a gas of impenetrable bosons released from a
harmonic trapping potential to a circle. The many-body dynamics is solved analytically and …

For many-particle systems with short-range interactions, the local (same point) particle-
particle pair correlation function represents a thermodynamic quantity that can be calculated …

We derive exact formulas for the expectation value of local observables in a one-
dimensional gas of bosons with point-wise repulsive interactions (Lieb–Liniger model) …
