Spinning fluids in the EinsteinCartan theory: A variational formulation
Abstract
In this work we propose a lagrangian for spinning fluids in the EinsteinCartan theory. The basic characteristic of the model is to consider each infinitesimal volume element as replicas of microrigid bodies. The theory obtained represents the thermodynamical equilibrium limit of a more general situation where dissipative processes due to spin take place. We outline the extension of such processes to the EinsteinCartan theory.
