Moreover, interactions between ultracold atoms, characterized by the s-wave scattering length a, can be tuned via magnetic Feshbach resonances, giving access to the regime of strong interactions. In this article, we investigate the condensation energy of a dilute spin-1/2 strongly interacting Fermi gas with a variable interaction strength. We show that the condensation energy can be measured by applying a chemical potential imbalance between the two spin states which is the analog of a magnetic… Expand

Finite-Temperature Equation of State of Polarized Fermions at Unitarity.
The complex Langevin method is used to study in a nonperturbative fashion the thermodynamics of a unitary Fermi gas over a wide range of temperatures and spin polarizations, showing results for the density equation of state, the magnetization, and the magnetic susceptibility. Expand
Collective oscillations of a trapped atomic gas in low dimensions and thermodynamics of one-dimensional Bose gas
Ultracold atoms are exceptional tools to explore the physics of quantum matter. In fact, the high degree of tunability of ultracold Bose and Fermi gases makes them ideal systems for quantumExpand
Mixtures of Bose and Fermi Superfluids
Manifestations of Quantum Physics at the thermodynamical level are found in a broadrange of physical systems. A famous example is superfluidity, discovered at the beginningof the 20th century andExpand
Quantum transport in ultracold atoms
Ultracold atoms confined by engineered magnetic or optical potentials are ideal to study phenomena otherwise difficult to realize or probe in the solid state, thanks to the ability to control theExpand
Sarma phase in relativistic and non-relativistic systems
We investigate the stability of the Sarma phase in two-component fermion systems in three spatial dimensions. For this purpose we compare strongly-correlated systems with either relativistic orExpand
