Spontaneous and Explicit Spacetime Symmetry Breaking in Einstein–Cartan Theory with Background Fields
Explicit and spontaneous breaking of spacetime symmetry under diffeomorphisms, local translations, and local Lorentz transformations due to the presence of fixed background fields is examined in Einstein–Cartan theory. In particular, the roles of torsion and violation of local translation invariance...
