From Lorentz-Chern-Simons to Massive Gravity in 2+1 dimensions
Abstract: We propose a generalization of Chiral Gravity, which follows from considering a Chern-Simons action for the spin connection with anti-symmetric contorsion. The theory corresponds to Topologically Massive Gravity at the chiral point non-minimally coupled to an additional scalar mode that ga...
