All chiral -algebra extensions of
Nishant Gupta, Nemani V. Suryanarayana
We show that there are four chiral -algebra extensions of algebra and construct them explicitly. We do this by a simple identification of each of the…
A Chiral - Symmetry of AdS Gravity
Nishant Gupta, Nemani V. Suryanarayana
Generalising the chiral boundary conditions of gravity for AdS gravity, we derive chiral locally AdS solutions in the Newman-Unti gauge consistent with a…
symmetry of gravity
Nishant Gupta, Partha Paul, Nemani V. Suryanarayana
We propose novel asymptotically locally flat boundary conditions for Einstein Gravity without cosmological constant in four dimensions that are consistent with the variational prin…
Constructing Carrollian CFTs
Nishant Gupta, Nemani V. Suryanarayana
We construct classical theories for scalar fields in arbitrary Carroll spacetimes that are invariant under Carrollian diffeomorphisms and Weyl transformations. When the local symme…
White holes in Einstein-aether theory
Ratindranath Akhoury, David Garfinkle, Nishant Gupta
We perform numerical simulations of gravitational collapse in Einstein-aether theory. We find that under certain conditions, the collapse results in the temporary formation of a wh…
