Thermodynamics of Born-Infeld Black Holes
Wissam A. Chemissany, Mees de Roo, Sudhakar Panda
We discuss the horizon structure for Born-Infeld black holes, in the context of Einstein-Born-Infeld gravity. We show that the entropy function formalism agrees with a direct calcu…
Quantum gravitational corrections to the stress-energy tensor around the rotating BTZ black hole
Dawood A. Kothawala, S. Shankaranarayanan, L. Sriramkumar
Modes emerging out of a collapsing black hole are red-shifted to such an extent that Hawking radiation at future null infinity consists of modes that have energies beyond the Planc…
On the dyon partition function in N=2 theories
Justin R. David
We study the entropy function of two N =2 string compactifications obtained as freely acting orbifolds of N=4 theories : the STU model and the FHSV model. The Gauss-Bonnet term for…
Free Fermions and Thermal AdS/CFT
Suvankar Dutta, Rajesh Gopakumar
The dynamics of finite temperature U(N) gauge theories on can be described, at weak coupling, by an effective unitary matrix model. Here we present an exact solution to these…
Bulk antisymmetric tensor fields in a Randall-Sundrum model
Biswarup Mukhopadhyaya, Somasri Sen, Soumitra SenGupta
We consider bulk antisymmetric tensor fields of various ranks in a Randall-Sundrum scenario. We show that, rank-2 onwards, the zero-modes of the projections of these fields on the…
alpha'-Corrections to Heterotic Superstring Effective Action Revisited
W. A. Chemissany, Mees de Roo, Sudhakar Panda
In this letter we establish that the supersymmetric R^2 effective action for the heterotic string, obtained from the supersymmetrisation of the Lorentz Chern-Simons term, is to ord…
