Anomalous specific heat jump in a two-component ultracold Fermi gas
Armen Sedrakian, Herbert Müther, Artur Polls
The thermodynamic functions of a Fermi gas with spin population imbalance are studied in the temperature-asymmetry plane in the BCS limit. The low temperature domain is characteriz…
Pairing in a two-component ultracold Fermi gas: phases with broken space symmetries
Armen Sedrakian, Jordi Mur-Petit, Artur Polls +1
We explore the phase diagram of a two-component ultracold atomic Fermi gas interacting with zero-range forces in the limit of weak-coupling. We focus on the dependence of the pairi…
Deformed Fermi surfaces in ultracold Fermi gases
Armen Sedrakian, Jordi Mur-Petit, Artur Polls +1
The superfluid transition in an ultracold two-component atomic Fermi gas is analyzed in the case where the two components have different densities. We describe a superfluid state w…
Pairing in two-dimensional boson-fermion mixtures
J. Mur-Petit, A. Polls, M. Baldo +1
The possibilities of pairing in two-dimensional boson-fermion mixtures are carefully analyzed. It is shown that the boson-induced attraction between two identical fermions dominate…
3He impurity excitation spectrum in liquid 4He
A. Fabrocini, A. Polls
We evaluate microscopically the excitation spectrum of the 3He impurity in liquid 4He at T=0 and compare it with the experimental curve at the equilibrium density. The adopted corr…
