Sub-leading contributions to the black hole entropy in the brick wall approach
Sudipta Sarkar, S. Shankaranarayanan, L. Sriramkumar
[Abridged] We compute the canonical entropy of a quantum scalar field around static and spherically symmetric black holes through the brick wall approach at the higher orders (in f…
Is Modified Chaplygin gas along with barotropic fluid responsible for acceleration of the Universe?
Writambhara Chakraborty, Ujjal Debnath
In this letter, we have considered a model of the universe filled with modified Chaplygin gas and another fluid (with barotropic equation of state) and its role in accelerating pha…
Entropy of BTZ black strings in the brick wall approach
H. K. Jassal, L. Sriramkumar
During the last few years, exact solutions that describe black holes that are bound to a two-brane in a four dimensional anti-de Sitter bulk have been constructed. In situations wh…
Randall-Sundrum with Kalb-Ramond field: return of the hierarchy problem?
Saurya Das, Anindya Dey, Soumitra SenGupta
We show that when the antisymmetric Kalb-Ramond field is included in the Randall-Sundrum scenario, although the hierarchy problem can be solved, it requires an extreme fine tuning…
