Non-Perturbative Prediction of the Ferromagnetic Transition in Repulsive Fermi Gases
Fermi Gases Ferromagnetic Transition
2011/7/21
It is generally believed that a dilute spin-1/2 Fermi gas with repulsive interactions can undergo a ferromagnetic phase transition to a spin-polarized state at a critical gas parameter $(k_{\text F}a)...
Traveling Dark Solitons in Superfluid Fermi Gases
Traveling Dark Solitons Superfluid Fermi Gases
2010/11/25
Families of dark solitons exist in superfluid Fermi gases. The energy-velocity dispersion and
number of depleted particles completely determines the dynamics of dark solitons on a slowly-
varying ba...
Induced p-wave superfluidity in strongly interacting imbalanced Fermi gases
Induced p-wave superfluidity imbalanced Fermi gases
2010/11/24
The induced interaction among the majority spin species, due to the presence of the minority
species, is computed for the case of a population-imbalanced resonantly-interacting Fermi gas.
Coexistence of pairing gaps in three-component Fermi gases
Coexistence of pairing gaps three-component Fermi gases
2010/11/25
We study a three-component superfluid Fermi gas in a spherically symmetric harmonic trap using the Bogoliubov-deGennes method. We predict a coexistence phase in which two pairing field order parameter...
Exactly solvable models and ultracold Fermi gases
Exactly solvable models ultracold Fermi gases
2010/11/23
Exactly solvable models of ultracold Fermi gases are reviewed via their thermodynamic Bethe Ansatz solution. Analytical and numerical results are obtained for the thermodynamics and ground state prope...
