Readdressing the hierarchy problem in a Randall-Sundrum scenario with bulk Kalb-Ramond background
Saurya Das, Anindya Dey, Soumitra SenGupta
We re-examine the fine tuning problem of the Higgs mass, when an antisymmetric two form Kalb-Ramond (KR) field is present in the bulk of a Randall-Sundrum (RS) braneworld. Taking i…
How robust is the entanglement entropy-area relation?
Saurya Das, S. Shankaranarayanan
We revisit the problem of finding the entanglement entropy of a scalar field on a lattice by tracing over its degrees of freedom inside a sphere. It is known that this entropy sati…
High frequency quasi-normal modes for black holes with generic singularities II: Asymptotically non-flat spacetimes
Archisman Ghosh, S. Shankaranarayanan, Saurya Das
The possibility that the asymptotic quasi-normal mode (QNM) frequencies can be used to obtain the Bekenstein-Hawking entropy for the Schwarzschild black hole -- commonly referred t…
Charged black holes in generalized dilaton-axion gravity
Sourav Sur, Saurya Das, Soumitra SenGupta
We study generic Einstein-Maxwell-Kalb-Ramond-dilaton actions, and derive conditions under which they give rise to static, spherically symmetric black hole solutions. We obtain new…
Is entanglement entropy proportional to area?
Morteza Ahmadi, Saurya Das, S. Shankaranarayanan
It is known that the entanglement entropy of a scalar field, found by tracing over its degrees of freedom inside a sphere of radius , is proportional to the area of the s…
