An Inhomogeneous Jacobi equation for minimal surfaces and perturbative change of Holographic Entanglement Entropy
Avirup Ghosh, Rohit Mishra
The change in Holographic entanglement entropy (HEE) for small fluctuations about pure anti De Sitter (AdS) is obtained by a perturbative expansion of the area functional in terms…
Massless charged particles: Cosmic censorship, and Third law of Black Hole Mechanics
C. Fairoos, Avirup Ghosh, Sudipta Sarkar
The formulation of the laws of black hole mechanics assumes the stability of black holes under perturbations in accordance with the "cosmic censorship hypothesis"(CCH). CCH prohibi…
On the physical process first law for dynamical black holes
Akash Mishra, Sumanta Chakraborty, Avirup Ghosh +1
Physical process version of the first law of black hole mechanics relates the change in entropy of a perturbed Killing horizon, between two asymptotic cross sections, to the matter…
Heavy stable charged tracks as signatures of non-thermal dark matter at the LHC : a study in some non-supersymmetric scenarios
Avirup Ghosh, Tanmoy Mondal, Biswarup Mukhopadhyaya
We consider two theoretical scenarios, each including a -odd sector and leading to an elementary dark matter candidate. The first one is a variant of the Type-III s…
