Gravitational field equations near an arbitrary null surface expressed as a thermodynamic identity
Sumanta Chakraborty, Krishnamohan Parattu, T. Padmanabhan
Previous work has demonstrated that the gravitational field equations in all Lanczos-Lovelock models imply a thermodynamic identity TdS=dE+PdV (where the variations are interpreted…

A Boundary Term for the Gravitational Action with Null Boundaries
Krishnamohan Parattu, Sumanta Chakraborty, Bibhas Ranjan Majhi +1
Constructing a well-posed variational principle is a non-trivial issue in general relativity. For spacelike and timelike boundaries, one knows that the addition of the Gibbons-Hawk…
