weak interaction p-wave superfluid fermi gas: low-temperature shear viscosity

The shear viscosity tensor of a superfluid fermi gas in a p-wave state with weak interactions was investigated using the boltzmann equation at low temperatures. therefore, transition probabilities of the binary collision, decay, and coalescence processes were considered for this purpose. theoretically, the dominant processes at low temperatures find to be the binary ones, whereas the elements of the shear viscosity (i.e., ) report to be proportional to . moreover, behaved as , and  was proportional to .
