Ultradilute quantum liquid drops
V. Cikojević, K. Dželalija, P. Stipanović +2
Using quantum Monte Carlo methods we have studied dilute Bose-Bose mixtures with attractive interspecies interaction in the limit of zero temperature. The calculations are exact wi…
Quantized superfluid vortex dynamics on cylindrical surfaces and planar annuli
Nils-Eric Guenther, Pietro Massignan, Alexander L. Fetter
Superfluid vortex dynamics on an infinite cylinder differs significantly from that on a plane. The requirement that a condensate wave function be single valued upon once encircling…
Bose polarons at finite temperature and strong coupling
Nils-Eric Guenther, Pietro Massignan, Maciej Lewenstein +1
The temperature dependence of a mobile impurity in a dilute Bose gas, the Bose polaron, is investigated for wide a range of impurity-bath interactions. Using a diagrammatic resumma…
Dipolar Bose Superstripes
R. Bombin, J. Boronat, F. Mazzanti
We study the superfluid properties of a system of fully polarized dipolar bosons moving in the plane. We focus on the general case where the polarization field forms an arbitr…
Andreev-Bashkin effect in superfluid cold gases mixture
Jacopo Nespolo, Grigori E. Astrakharchik, Alessio Recati
We study a mixture of two superfluids with density-density and current-current (Andreev-Bashkin) interspecies interactions. The Andreev-Bashkin coupling gives rise to a dissipation…
Composite boson description of a low density gas of excitons
A. E. Golomedov, Yu. E. Lozovik, G. E. Astrakharchik +1
Ground state properties of a fermionic Coulomb gas are calculated using the fixed-node diffusion Monte Carlo method. The validity of the composite boson description is tested for d…
