Two-dimensional Bose and Fermi gases beyond weak coupling
Guilherme Franca, Andre LeClair, Joshua Squires
Using a formalism based on the two-body S-matrix we study two-dimensional Bose and Fermi gases with both attractive and repulsive interactions. Approximate analytic expressions, va…
Metastability of Bose and Fermi gases on the upper branch
Andre LeClair, Itzhak Roditi, Joshua Squires
We study three dimensional Bose and Fermi gases in the upper branch, a phase defined by the absence of bound states in the repulsive interaction regime, within an approximation tha…
Virial coefficients for Bose and Fermi trapped gases beyond the unitary limit: an S-Matrix approach
E. Marcelino, A. Nicolai, I. Roditi +1
We study the virial expansion for three-dimensional Bose and Fermi gases at finite temperature using an approximation that only considers two-body processes and is valid for high t…
Quantum Bose and Fermi gases with large negative scattering length in the 2-body S-matrix approximation
Andre LeClair, Edgar Marcelino, Andre Nicolai +1
We study both Bose and Fermi gases at finite temperature and density in an approximation that sums an infinite number of many body processes that are reducible to 2-body scattering…
On the viscosity to entropy density ratio for unitary Bose and Fermi Gases
André LeClair
We calculate the ratio of the viscosity to the entropy density for both Bose and Fermi gases in the unitary limit using a new approach to the quantum statistical mechanics of gases…
S-matrix approach to quantum gases in the unitary limit II: the three-dimensional case
Pye-Ton How, André LeClair
A new analytic treatment of three-dimensional homogeneous Bose and Fermi gases in the unitary limit of negative infinite scattering length is presented, based on the S-matrix appro…
