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…
Higgs mode in the quench dynamics of a confined ultracold Fermi gas in the BCS regime
S. Hannibal, P. Kettmann, M. D. Croitoru +3
The Higgs amplitude mode of the order parameter of an ultracold confined Fermi gas in the BCS regime after a quench of the coupling constant is analyzed theoretically. Characterist…
Atypical BCS-BEC crossover induced by quantum-size effects
A. A. Shanenko, M. D. Croitoru, A. V. Vagov +3
Quantum-size oscillations of the basic physical characteristics of a confined fermionic condensate are a well-known phenomenon. Its conventional understanding is based on the singl…
