Chiral Gravity in Three Dimensions
Three dimensional Einstein gravity with negative cosmological constant −1/l2 deformed by a gravitational Chern-Simons action with coefficient 1/μ is studied in an asymptotically AdS3 spacetime. It is argued to violate unitary or positivity for generic μ due to negativeenergy massive gravitons. However at the critical value μl = 1, the massive gravitons disappear and BTZ black holes all have mas...
متن کاملChiral gravity in two dimensions
It is shown that conformal matter with cL 6= cR can be consistently coupled to two-dimensional ‘frame’ gravity. The theory is quantized, following David, and Distler and Kawai, using the derivation of their ansatz due to Mavromatos and Miramontes, and D’Hoker and Kurzepa. New super-selection rules are found by requiring SL(2,C) invariance of correlation functions on the plane. There is no analo...
متن کاملMassive gravity in three dimensions.
A particular higher-derivative extension of the Einstein-Hilbert action in three spacetime dimensions is shown to be equivalent at the linearized level to the (unitary) Pauli-Fierz action for a massive spin-2 field. A more general model, which also includes "topologically-massive" gravity as a special case, propagates the two spin-2 helicity states with different masses. We discuss the extensio...
متن کاملGravity waves in three dimensions
We find the explicit forms of the anti–de Sitter plane, anti–de Sitter spherical, and pp waves that solve both the linearized and exact field equations of the most general higher derivative gravity theory in three dimensions. As a subclass, we work out the six-derivative theory and the critical version of it where the masses of the two spin-2 excitations vanish and the spin-0 excitations decouple.
متن کاملNoncommutative Einstein-AdS Gravity in three Dimensions
We present a Lorentzian version of three-dimensional noncommutative Einstein-AdS gravity by making use of the Chern-Simons formulation of pure gravity in 2+1 dimensions. The deformed action contains a real, symmetric metric and a real, antisymmetric tensor that vanishes in the commutative limit. These fields are coupled to two abelian gauge fields. We find that this theory of gravity is invaria...
