Finite Temperature Phase Diagram of a Two-Component Fermi Gas with Density Imbalance
Lianyi He, Meng Jin, Pengfei Zhuang
We investigated possible superfluid phases at finite temperature in a two-component Fermi gas with density imbalance. In the frame of a general four-fermion interaction theory, we…
Fermion Cooper Pairing with Unequal Masses: Standard Field Theory Approach
Lianyi He, Meng Jin, Pengfei Zhuang
The fermion Cooper pairing with unequal masses is investigated in a standard field theory approach. We derived the superfluid density and Meissner mass squared of the U(1) gauge fi…
Sound Velocity and Meissner Effect in Light-heavy Fermion Pairing Systems
Lianyi He, Meng Jin, Pengfei Zhuang
In the frame of a four fermion interaction theory, we investigated the collective excitation in light-heavy fermion pairing systems. When the two species of fermions posses differe…
LOFF Pairing vs. Breached Pairing in Asymmetric Fermion Superfluids
Lianyi He, Meng Jin, Pengfei Zhuang
A general analysis for the competition between breached pairing (BP) and LOFF pairing mechanisms in asymmetric fermion superfluids is presented in the frame of a four fermion inter…
