Universal quantum viscosity in a unitary Fermi gas.
Unitary Fermi gases, first observed by our group in 2002, have been widely studied as they provide model systems for tabletop research on a variety of strongly coupled systems, including the high temperature superconductors, quark-gluon plasmas and neutron stars. A two component6Li unitary Fermi …

Thermodynamics and solitonic excitations of a strongly-interacting Fermi gas
… solitonic excitations of a strongly-interacting Fermi gas, realized with 6Li atoms at a Feshbach resonance where the scattering length is large. The strongly-interacting Fermi gas, also called the unitary Fermi gas, exhibits a novel superfluidity that is a crossover of the Bose-Einstein …

Thermodynamic and hydrodynamic behaviour of interacting Fermi gases
Fermionic matter is ubiquitous in nature, from the electrons in metals and semiconductors or the neutrons in the inner crust of neutron stars, to gases of fermionic atoms, like 40K or 6Li that can be created and studied under laboratory conditions. It is especially interesting to study these …

Fermi Mixtures: Effects of Engineered Confinements
… review the theory of the normal state of the unitary Fermi gas at T = 0 and the main properties of the normal-to-superfluid transition. Then we study the trapped gas under adiabatic rotation, i.e., avoiding the formation of vortices. We show that for polarized systems the rotation enhances the …

A continuum path integral approach to the simulation of a unitary gas
… an investigation by simulation of a unpolarized fermionic unitary gas system composed of two interacting fermionic species. While these species do not interact amongst themselves, they interact with each other using a pairwise zero-range delta function potential that has been tuned to unitarity …
