Holographic symmetry algebra for the MHV sector revisited
Shamik Banerjee, Mousumi Maitra, Raju Mandal +1
We revisit the holographic symmetry algebra in the MHV sector. We find an infinite dimensional Abelian symmetry algebra whose generators are the conformally soft negative helicity…
BMS Goldstone modes near the horizon of a Kerr black hole are thermal
Mousumi Maitra, Debaprasad Maity, Bibhas Ranjan Majhi
Near horizon Bondi-Metzner-Sachs (BMS) like symmetry is spontaneously broken by the black hole background itself and hence gives rise to Goldstone mode. The associated Goldstone mo…
Diffeomorphism symmetries near a timelike surface in black hole spacetime
Mousumi Maitra, Debaprasad Maity, Bibhas Ranjan Majhi
Recently symmetries of gravity and gauge fields in the asymptotic regions of spacetime have been shown to play vital role in their low energy scattering phenomena. Further, for the…
Near horizon symmetries, emergence of Goldstone modes and thermality
Mousumi Maitra, Debaprasad Maity, Bibhas Ranjan Majhi
For a long time it is believed that black hole horizon are thermal and quantum mechanical in nature. The microscopic origin of this thermality is the main question behind our prese…
Symmetries near a generic charged null surface and associated algebra: an off-shell analysis
Mousumi Maitra, Debaprasad Maity, Bibhas Ranjan Majhi
To understand the underlying degrees of freedom, near horizon symmetry analysis of a black has gain significant interest in the recent past. In this paper we generalized those anal…
