Accidental Symmetry Near Extreme Spinning Black Holes
Avik Banerjee, Achilleas P. Porfyriadis, Grant N. Remmen
Near the horizon of extremal charged black holes, an accidental symmetry is known to act on zero-temperature perturbations, transforming them into finite-temperature ones. In this…

Dark matter cooling during early matter-domination boosts sub-earth halos
Avik Banerjee, Debtosh Chowdhury, Arpan Hait +1
The existence of an early matter-dominated epoch prior to the Big Bang Nucleosynthesis may lead to a scenario where the thermal dark matter cools faster than plasma before the radi…

Bounds on deformation from entanglement
Avik Banerjee, Pratik Roy
Motivated by the existence of complex spectrum in -deformed CFTs, in this paper we revisit the broadly studied topic of (holographic) entanglement entropy in the deformed…
