Superfluid behavior of a Bose–Einstein condensate in a random potential [PDF]
New Journal of Physics, 2015 We investigate the relation between Bose–Einstein condensation (BEC) and superfluidity in the ground state of a one-dimensional model of interacting bosons in a strong random potential.

Thermo-optical interactions in a dye-microcavity photon Bose–Einstein condensate [PDF]
New Journal of Physics, 2017 Superfluidity and Bose–Einstein condensation are usually considered as two closely related phenomena. Indeed, in most macroscopic quantum systems, like liquid helium, ultracold atomic Bose gases, and exciton-polaritons, condensation and superfluidity ...

Superfluidity of Dipolar Excitons in a Double Layer of α − T3 with a Mass Term [PDF]
Nanomaterials, 2022 We predict Bose-Einstein condensation and superfluidity of dipolar excitons, formed by electron-hole pairs in spatially separated gapped hexagonal α−T3 (GHAT3) layers.

Magnetohydrodynamics as Superfluidity [PDF]
Physical Review Letters, 2019 We show that relativistic magnetohydrodynamics (MHD) can be recast as a novel theory of superfluidity. This new theory formulates MHD just in terms of conservation equations, including dissipative effects, by introducing appropriate variables such as a magnetic scalar potential, and providing necessary and sufficient conditions to obtain equilibrium ...

Spin superfluidity and long-range transport in thin-film ferromagnets
Physical Review Letters, 2015 In ferromagnets, magnons may condense into a single quantum state. Analogous to superconductors, this quantum state may support transport without dissipation.

Zonal Estimators for Quasiperiodic Bosonic Many-Body Phases [PDF]
Entropy, 2022 In this work, we explore the relevant methodology for the investigation of interacting systems with contact interactions, and we introduce a class of zonal estimators for path-integral Monte Carlo methods, designed to provide physical information about ...

Porous Materials for Atmospheric Water Harvesting [PDF]
ChemistryOpen, 2023 Atmospheric Water Harvesting (AWH) using porous adsorbents is emerging as a promising solution to combat water shortage. Thus, a clearer understanding of the developing trends and optimization strategies of different porous adsorbents can be extremely ...

Physical Review Research, 2020 We propose a superfluid phase of ``many-fracton system'' in which charge and total dipole moments are conserved quantities. In this work, both microscopic model and long-wavelength effective theory are analyzed. We start with a second quantized microscopic model and formulate the coherent-state path-integral representation.

Rabi Coupled Fermions in the BCS–BEC Crossover
Condensed Matter, 2022 We investigate the three-dimensional BCS–BEC crossover in the presence of a Rabi coupling, which strongly affects several properties of the system, such as the chemical potential, the pairing gap and the superfluid density.
