In this work we have presented the one-loop calculation of the bulk viscosityof a system of rotating, hot and dense spin 1/2 fermions within the frameworkof Kubo formalism calculated from correlation functions of fields which in turnis used to calculate the spectral function of energy-momentum tensors. Thecalculation has been done in curved space by the help of tetrad formalism,where the the gamma matrices in this set-up assume their generic structure bybecoming space dependent. The techniques of thermal field theory have beenemployed which take into account the three energy scales viz. temperature,chemical potential and angular velocity into account in the Matsubara frequencysummation. The study has been performed in the ambience of very large angularvelocities, ranging from 0.1 to 1.0 GeV. The fermion propagator used in thiswork is appropiate for the regime of large angular velocities. We explore thebehaviour of bulk viscosity with angular velocity, temperature and chemicalpotential through our plots.
