Weyssenhoff fluid dynamics in general relativity using a 1+3 covariant approach

S. D. Brechet, M. P. Hobson, A. N. Lasenby

The Weyssenhoff fluid is a perfect fluid with spin where the spin of the matter fields is the source of torsion in an Einstein-Cartan framework. Obukhov and Korotky showed that thi…
