Confinement and finite-range effects in a quasi-two-dimensional gas of fermionic dimers
Giovanni Midei, Jordi Boronat, Grigory E. Astrakharchik
We investigate the ground-state properties of ultracold two-component Fermi gases in the presence of a transverse harmonic potential, focusing on the strongly interacting regime in…
Bose-Einstein condensation on axially-symmetric surfaces
A. Tononi, G. E. Astrakharchik
We investigate the phenomenon of Bose-Einstein condensation in ideal bosonic gases confined to axially-symmetric surfaces of revolution. The single-particle Schrödinger equation i…
Dynamic correlations in Calogero-Sutherland model
G. Lleopart Motis, D. M. Gangardt, M. Pustilnik +1
The Calogero-Sutherland model represents a paradigmatic example of an integrable quantum system with applications ranging from cold atoms to random matrix theory. Combining sum rul…
Universal properties of dipolar Bose polarons in two dimensions
Juan Sánchez-Baena, Luis A. Peña Ardila, Grigory Astrakharchik +1
We study the quasiparticle properties of a dipolar impurity immersed in a two-dimensional dipolar bath. We use the ab-initio Diffusion Monte Carlo technique to determine the polaro…
Universal relations in Bose gases with power-law interactions in two and three dimensions
Nina S. Voronova, Elena V. Skirdova, I. L. Kurbakov +1
We derive universal relations between thermodynamic quantities and the pair distribution function for bosons interacting via power-law interactions in three and two dimensions. We…
Temperature-induced miscibility of impurities in trapped Bose gases
G. Pascual, T. Wasak, A. Negretti +2
We study the thermal properties of impurities embedded in a repulsive Bose gas under a harmonic trapping potential. In order to obtain exact structural properties in this inhomogen…
