Null reduction and dynamical realization of Carrollian conformal symmetries
Ashis Saha, Rabin Banerjee, Sunandan Gangopadhyay
We start from a Lorentzian action in a deformed light-cone background and applying the method of null reduction leads to a Carrollian action in one lower spacetime dimensions. We a…

Effect of non-conformal deformation on the gapped quasi-normal modes and the holographic implications
Ashis Saha, Sunandan Gangopadhyay
The spectral curve of quasinormal modes for a massive real scalar field in the background of a non-conformal black brane geometry has been obtained by utilizing a Frobenius type ne…
