Cavity nonlinear optics with layered materials
Nanophotonics, Volume 7, Issue 2, Page 355-370, January 2018., 2018 Abstract Unprecedented material compatibility and ease of integration, in addition to the unique and diverse optoelectronic properties of layered materials, have generated significant interest in their utilization in nanophotonic devices. While initial nanophotonic experiments with layered materials primarily focused on light sources, modulators, and ...

BCS-BEC Crossover in a Random External Potential [PDF]
Physical Review Letters, 2007 We investigate the ground state properties of a disordered superfluid Fermi gas across the BCS-BEC (Bose Einstein condensate) crossover. We show that, for weak disorder, both the depletion of the condensate fraction of pairs and the normal fluid density exhibit a nonmonotonic behavior as a function of the interaction parameter $1/k_Fa$, reaching their ...

Yu-Shiba-Rusinov states, the BCS-BEC crossover, and the exact solution in the flat-band limit [PDF]
, 2022 We study the subgap Yu-Shiba-Rusinov (YSR) states in the Richardson's model of a superconductor with a magnetic impurity for different electron pairing strengths from the weak-coupling Bardeen-Cooper-Schrieffer (BCS) regime to the strong-coupling Bose ...

The Dirac spectrum and the BEC-BCS crossover in QCD at nonzero isospin asymmetry
Particles, 2020 For large isospin asymmetries, perturbation theory predicts the quantum chromodynamic (QCD) ground state to be a superfluid phase of u and d ¯ Cooper pairs.

Two-body correlation functions in nuclear matter with $np$ condensate
, 2006 The density, spin and isospin correlation functions in nuclear matter with a neutron-proton ($np$) condensate are calculated to study the possible signatures of the BEC-BCS crossover in the low-density region.
