DOI: 10.1002/andp.201800316
Abstract: We investigate the emergence of superfluid p=p_x+ip_y phases in an ultracold gas of dipolar Fermi molecules lying in two parallel square lattices in 2D. As shown by a two body study, dipole moments oriented in… read more here.

DOI: 10.1038/s41586-019-1408-8
Abstract: Although the possibility of spatial variations in the superfluid of unconventional, strongly correlated superconductors has been suggested1–7, it is not known whether such inhomogeneities—if they exist—are driven by disorder, strong scattering or other factors. Here… read more here.

DOI: 10.1103/physreva.100.053620
Abstract: We study the quantum fluctuations in the condensates of a mixture of bosonic atoms and molecules with interspecies p-wave interaction. Our analysis shows that the quantum phase of coexisting atomic and molecular condensates is unstable… read more here.

DOI: 10.1103/physreva.101.023605
Abstract: The full statistical distribution of the superfluid fraction characterizing one-dimensional Bose gases in random potentials is discussed. Rare configurations with extreme fluctuations of the disorder potential can fragment the condensate and reduce the superfluid fraction… read more here.

DOI: 10.1103/physrevb.100.174517
Abstract: We calculate the superfluid weight and the polarization amplitude for the one-dimensional bosonic Hubbard model focusing on the strong-coupling regime. Other than analytic calculations we apply two methods: variational Monte Carlo based on the Baeriswyl… read more here.

DOI: 10.1103/physrevb.107.144511
Abstract: Vortices are topological defects associated with superfluids and superconductors, which, when mobile, dissipate energy destroying the dissipation-less nature of the superfluid. The nature of this"quantum dissipation"is rooted in the quantum physical nature of the problem,… read more here.

Abstract: Recently, Allmond and Wood [Phys. Lett. B 767, 226 (2017)] were able to extract the three moments of inertia $I_k$ of a dozen of superfluid triaxial nuclei from experimental data. The observed dependence of the… read more here.

DOI: 10.1103/physrevd.107.086005
Abstract: We have extended our previous work [1] on rotating holographic superfluids to include Lifshitz scaling. Presence of this scaling breaks relativistic invariance of the boundary superfluid system and indicates the existence of a Lifshitz fixed… read more here.
