Dressed Fock Spaces in Gauge Theory and Gravity
Sangmin Choi, Prahar Mitra
Four-dimensional gauge and gravitational theories exhibit long-range interactions that require asymptotic particles to be dressed by clouds of soft photons and gravitons. Faddeev-K…
Effective density matrix for vacua in asymptotically flat gravity
Temple He, Prahar Mitra, Kathryn M. Zurek
We explicitly construct the density matrix associated to the vacuum state of a large spherically symmetric causal diamond of area in four-dimensional asymptotically flat gravit…
A Holographic Model for Soft Photons and Gravitons in Four Dimensions
Sangmin Choi, Prahar Mitra
We construct a two-dimensional action on the celestial sphere that describes the infrared sector of Abelian gauge and gravitational theories in four dimensions. In particular, we u…
An On-Shell Derivation of the Soft Effective Action in Abelian Gauge Theories
Temple He, Prahar Mitra, Allic Sivaramakrishnan +1
We derive the soft effective action in -dimensional abelian gauge theories from the on-shell action obeying Neumann boundary conditions at timelike and null infinity and Dir…
Quantum Mechanics of a Spherically Symmetric Causal Diamond in Minkowski Spacetime
Mathew W. Bub, Temple He, Prahar Mitra +2
We construct the phase space of a spherically symmetric causal diamond in -dimensional Minkowski spacetime. Utilizing the covariant phase space formalism, we identify the re…
Charged Rotating Hairy Black Holes in AdS: Unveiling their Secrets
Oscar J. C. Dias, Prahar Mitra, Jorge E. Santos
Using a mix of analytical and numerical methods, we construct new rotating, charged "hairy" black hole solutions of , gauged supergravity that are dual, via the A…
