Interference-induced surface superconductivity:Enhancement by tuning the Debye energy
Yunfei Bai, Yajiang Chen, M. D. Croitoru +3
In the usual perception, surface superconductivity is associated with the surface nucleation of a superconducting condensate above the upper critical field in type-II superconducto…
Multiband superconductors with degenerate excitation gaps
Paulo J. F. Cavalcanti, Tiago T. Saraiva, J. Albino Aguiar +3
There is a tacit assumption that multiband superconductors are essentially the same as multigap superconductors. More precisely, it is usually assumed that the number of excitation…
Persistent oscillations of the order parameter and interaction quench phase diagram for a confined Bardeen-Cooper-Schrieffer Fermi gas
S. Hannibal, P. Kettmann, M. D. Croitoru +2
We present a numerical study of the interaction quench dynamics in a superfluid ultracold Fermi gas confined in a three-dimensional cigar-shaped harmonic trap. In the present paper…
Dynamical vanishing of the order parameter in a confined Bardeen-Cooper-Schrieffer Fermi gas after an interaction quench
S. Hannibal, P. Kettmann, M. D. Croitoru +2
We present a numerical study of the Higgs mode in an ultracold confined Fermi gas after an interaction quench and find a dynamical vanishing of the superfluid order parameter. Our…
Pure Goldstone mode in the quench dynamics of a confined ultracold Fermi gas in the BCS-BEC crossover regime
P. Kettmann, S. Hannibal, M. D. Croitoru +2
We present a numerical study of the dynamic response of a confined superfluid Fermi gas to a rapid change of the scattering length (i.e., an interaction quench). Based on a fully m…
Quench dynamics of a confined ultracold Fermi gas: Direct visibility of the Goldstone mode in the single-particle excitations
P. Kettmann, S. Hannibal, M. D. Croitoru +2
We present a numerical study of a confined ultracold Fermi gas showing that the Goldstone mode of the BCS gap is directly visible in the dynamics of the single-particle excitations…
