Quasi-Normal Modes in Topologically Massive Gravity
نویسندگان
چکیده
We determine the black hole quasi-normal mode spectrum for tensor perturbations in topologically massive AdS-gravity. In the special case of chiral gravity quasi-normal modes are absent despite of the presence of a horizon. In the process we uncover a simple algebraic structure in the quasi normal modes spectrum: the tower of QNM’s consists of descendents of a ”chiral highest weight” QNM which in turn satisfies a first oder equation.

Quasi-Normal Modes for Logarithmic Conformal Field Theory
We generalize the one-to one correspondence between quasi normal modes in 3dimensional anti deSitter black holes and the poles of the retarded correlators in the boundary conformal field theory to include logarithmic operators in the latter. This analysis is carried out explicitly for the logarithmic mode in chiral topologically massive gravity. [email protected]
متن کاملRenormalizability of Topologically Massive Gravity
We consider renormalizability of topologically massive gravity in three space-time dimensions. With a usual parametrization of the metric tensor, we establish the statement that topologically massive gravity is in fact renormalizable. In this proof, we make use of not only a recently found, new infrared regularization method of scalar mode but also a covariant ultraviolet regulator with a speci...
متن کاملConsistent boundary conditions for cosmological topologically massive gravity at the chiral point
We show that cosmological topologically massive gravity at the chiral point allows not only Brown–Henneaux boundary conditions as consistent boundary conditions, but slightly more general ones which encompass the logarithmic primary found in 0805.2610 as well as all its descendants. e-mail: [email protected] e-mail: [email protected] Cosmological topologically massive gravity [1] (...
متن کاملStability of warped AdS3 vacua of topologically massive gravity
AdS3 vacua of topologically massive gravity (TMG) have been shown to be perturbatively unstable for all values of the coupling constant except the chiral point μl = 1. We study the possibility that the warped vacua of TMG, which exist for all values of μ, are stable under linearized perturbations. In this paper, we show that spacelike warped AdS3 vacua with Compère-Detournay boundary conditions...
متن کاملA note on positive energy of topologically massive gravity
I review how " classical SUGRA " embeddability establishes positive energy E for D = 3 topologically massive gravity (TMG), with or without a cosmological term, a procedure familiar from D = 4 Einstein gravity (GR). It also provides explicit expressions for E. In contrast to GR, E is not manifestly positive, due to the peculiar two-term nature of TMG.
