We review the BCS (Bardeen–Cooper–Schrieffer)–BEC (Bose–Einstein condensation)
crossover phenomenon discussed in an ultracold Fermi atomic gas and a neutron superfluid …

The field of two-dimensional (2D) materials-based nanophotonics has been growing at a
rapid pace, triggered by the ability to design nanophotonic systems with in situ control …

We discuss the BCS-BEC crossover in a degenerate Fermi gas of two hyperfine states
interacting close to a Feshbach resonance. We show that, by including fluctuation …

We investigate strong-coupling superfluidity in a uniform two-component gas of ultracold
Fermi atoms attractively interacting via quasimolecular bosons associated with a Feshbach …

We investigate the thermodynamics and signatures of a polariton condensate over a range
of densities, using a model of microcavity polaritons with internal structure. We determine a …

We propose a theoretical idea to use an ultracold Fermi gas as a quantum simulator for the
study of the low-density region of a neutron-star interior. Our idea is different from the …

The superfluid density is a fundamental quantity describing the response to a rotation as
well as in two-fluid collisional hydrodynamics. We present extensive calculations of the …

We theoretically investigate coherent optical excitations of collective modes in two-band
BCS superconductors, which accommodate two Higgs modes and one Leggett mode …

We investigate single-particle excitations and strong-coupling effects in the BCS-BEC
crossover regime of a superfluid Fermi gas. Including phase and amplitude fluctuations of …

We present a stability analysis on a driven-dissipative electron-hole condensate in the BCS
(Bardeen-Cooper-Schrieffer)–BEC (Bose-Einstein condensation) crossover region …
