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: 10.1007/jhep04(2025)172
Abstract: We investigate the linearized stability and causality properties of relativistic viscous superfluid hydrodynamics. The Landau-Lifshitz-Clark-Putterman formulation for the theory of relativistic viscous superfluids suffers from the same instability and acausality issues as the relativistic Navier-Stokes… read more here.

Abstract: Controlling the coupling between different degrees of freedom in many-body systems is a powerful technique for engineering novel phases of matter. We create a bilayer system of two-dimensional (2D) ultracold Bose gases and demonstrate the… 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/lcgr-bqcv
Abstract: A promising path to realizing higher superconducting transition temperatures $T_c$ is the strategic engineering of artificial heterostructures. For example, quantum materials could, in principle, be coupled with other materials to produce a more robust superconducting… 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.

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.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.
