Superfluid critical temperature in 3D Fermi gas with repulsion
D. V. Efremov, M. S. Mar'enko, M. A. Baranov +1
The critical temperature of a superfluid phase transition in a Fermi gas with repulsive interaction is found. The influence of a magnetic field on the transition is analyzed. The e…
Low energy collective excitations in a superfluid trapped Fermi gas
M. A. Baranov, D. S. Petrov
We study low energy collective excitations in a trapped superfluid Fermi gas, that describe slow variations of the phase of the superfluid order parameter. Well below the critical…
Single-particle excitations and the order parameter for a trapped superfluid Fermi gas
M. A. Baranov
We reveal a strong influence of a superfluid phase transition on the character of single-particle excitations of a trapped neutral-atom Fermi gas. Below the transition temperature…
Critical temperature and Ginzburg-Landau equation for a trapped Fermi gas
M. A. Baranov, D. S. Petrov
We discuss a superfluid phase transition in a trapped neutral-atom Fermi gas. We consider the case where the critical temperature greatly exceeds the spacing between the trap level…
