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 is…
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…
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…
Supersolid-Superfluid phase separation in the extended Bose-Hubbard model
Korbinian Kottmann, Andreas Haller, Antonio Acín +2
Recent studies have suggested a new phase in the extended Bose-Hubbard model in one dimension at integer filling [1,2]. In this work, we show that this new phase is phase-separated…
Ionic polaron in a Bose-Einstein condensate
G. E. Astrakharchik, L. A. Peña Ardila, R. Schmidt +2
The presence of strong interactions in a many-body quantum system can lead to a variety of exotic effects. Here we show that even in a comparatively simple setup consisting of a ch…
