Chiral Topologically Massive Gravity and Extremal B-F Scalars
نویسنده
چکیده
At a critical “chiral” coupling, topologically massive gravity with a negative cosmological constant exhibits several unusual features, including the emergence of a new logarithmic branch of solutions and a linearization instability for certain boundary conditions. I show that at this coupling, the linearized theory may be parametrized by a free scalar field at the Breitenlohner-Freedman bound, and use this description to investigate these features. email: [email protected]

Quasi-Normal Modes in Topologically Massive Gravity
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 ...
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 کاملCanonical analysis of cosmological topologically massive gravity at the chiral point
Wolfgang Kummer was a pioneer of two-dimensional gravity and a strong advocate of the first order formulation in terms of Cartan variables. In the present work we apply Wolfgang Kummer's philosophy, the 'Vienna School approach', to a specific three-dimensional model of gravity, cos-mological topologically massive gravity at the chiral point. Exploiting a new Chern–Simons representation we perfo...
متن کاملDistended Topologically Massive Electrodynamics
We extend topologically massive electrodynamics, both by adding a higher derivative action to cast the entire three-term model in Chern-Simons (CS) form, and by embedding it in an AdS background. It can then be written as the sum of two CS terms, one of which vanishes at the “chiral” point, in analogy with its gravitational topologically massive counterpart. Separately we treat pure CS electrod...
متن کاملSpinor Couplings to Dilaton Gravity induced by the Dimensional Reduction of Topologically Massive Gravity
A Dirac spinor is coupled to topologically massive gravity and the D = 3 dimensional action is reduced toD = 2 dimensions with a metric that includes both the electromagnetic potential 1-form A and a dilaton scalar φ. The reduced, electrically charged spinor is made a mass eigenstate with a (local) chiral rotation. The non-trivial interactions thus induced are discussed. [email protected] ...
