Mapping Tachyon effective field theory to a subsector of Klein-Gordon theory
P. V. Athira, Ashik H, Priyadarshi Paul
On an unstable D-brane, the rolling of the tachyon away from the maximum of its potential is described by time-dependent solutions in string theory. Subsequent analysis leads to an…
Interacting Fields at Spatial Infinity
Anupam A. H, P. V. Athira, Priyadarshi Paul +1
We study the properties of massive fields extrapolated to the blowup of spatial infinity (), extending the program initiated in arXiv:2207.06406. In the free theory, we…
Holography of information in de Sitter space
Tuneer Chakraborty, Joydeep Chakravarty, Victor Godet +2
We study the natural norm on the space of solutions to the Wheeler-DeWitt equation in an asymptotically de Sitter spacetime. We propose that the norm is obtained by integrating the…
The Hilbert space of de Sitter quantum gravity
Tuneer Chakraborty, Joydeep Chakravarty, Victor Godet +2
We obtain solutions of the Wheeler-DeWitt equation with positive cosmological constant for a closed universe in the large-volume limit. We argue that this space of solutions provid…
