Hyperfluid - a model of classical matter with hypermomentum
Yuri N. Obukhov, Romualdo Tresguerres
Abstract
A variational theory of a continuous medium is developed the elements of which carry momentum and hypermomentum (hyperfluid). It is shown that the structure of the sources in metric-affine gravity is predetermined by the conservation identities and, when using the Weyssenhoff ansatz, these explicitly yield the hyperfluid currents.
