Transport in the Presence of an Effective Range: Comparing the Shear and Bulk Viscosities

The transport properties of atomic gases depend sensitively on the scattering between individual particles. These interactions are described, to the lowest order, by an energy independent constant, the scattering length for s-wave and scattering volume for p-wave case. However, the higher order terms, like the effective range, are needed in some circumstances. In this talk we discuss how the effective range alters the bulk and shear viscosity in both s- and p-wave Fermi gases in three dimensions, and whether the effective range is relevant in describing the dynamics.​
