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 …

Long-lived excited states of interacting quantum systems that retain quantum correlations
and evade thermalization are of great fundamental interest. We create nonthermal states in …

We use exact quantum Monte Carlo techniques to study the properties of quantum droplets
in two-component bosonic mixtures with contact interactions in one spatial dimension. We …

Motivated by the calculation of correlation functions in inhomogeneous one-dimensional
(1d) quantum systems, the 2d Inhomogeneous Gaussian Free Field (IGFF) is studied and …

We present a comprehensive review on the state-of-the-art of the approximate analytic
approaches describing the finite-temperature thermodynamic quantities of the Lieb-Liniger …

We investigate the breathing mode and the stability of a quantum droplet in a tightly trapped
one-dimensional dipolar gas of bosonic atoms. When the droplet with a flat-top density …

Probing the radial collective oscillation of a trapped quantum system is an accurate
experimental tool to investigate interactions and dimensionality effects. We consider a fully …

We introduce a model of trapped bosons with contact interactions as well as Coulomb
repulsion or gravitational attraction in one spatial dimension. We find the exact ground-state …

We study the breathing (monopole) oscillations and their dam** in a harmonically trapped
onedimensional (1D) Bose gas in the quasicondensate regime using a finite-temperature …
