2+1 dimensional gravity in AAdS spacetimes with spatial wormhole slices: Reduced phase space dynamics and the BTZ black hole
Anurag Kaushal, Naveen S. Prabhakar, Spenta R. Wadia
We solve Einstein's equations with negative cosmological constant in dimensions in the Hamiltonian formulation. The spacetime has the topology of where $…
A gauge invariant Hamiltonian evolution across the black hole horizon in asymptotically AdS spacetimes
Anurag Kaushal, Naveen S. Prabhakar, Spenta R. Wadia
We study the quantum dynamics of a probe scalar field in the background of a black hole in AAdS spacetime in the Hamiltonian formulation of general relativity in the maximal slicin…
Quantum Scalar Field Dynamics On A Maximally Sliced Two-sided AdS Black Hole Spacetime
Anurag Kaushal, Naveen S. Prabhakar, Spenta R. Wadia
We study the semi-classical dynamics of a scalar field in the background of a black hole in an asymptotically AdS (AAdS) spacetime, in the framework of the Hamiltonian formulation…
Emergent Time in Hamiltonian General Relativity
Anurag Kaushal, Naveen S. Prabhakar, Spenta R. Wadia
In this paper we introduce a definition of time that emerges in terms of the geometry of the configuration space of a dynamical system. We illustrate this, using the Hamilton-Jacob…
Meson spectrum of QCD with Quarks in Large Representations
Anurag Kaushal, Naveen S. Prabhakar, Spenta R. Wadia
We consider quantum chromodynamics in dimensions with a single quark in the spin representation of the gauge group and study the theory in the large li…
Entanglement Entropy in Internal Spaces and Ryu-Takayanagi Surfaces
Sumit R. Das, Anurag Kaushal, Gautam Mandal +3
We study minimum area surfaces associated with a region, , of an internal space. For example, for a warped product involving an asymptotically space and an internal space…
A Microscopic Model of Black Hole Evaporation in Two Dimensions
Adwait Gaikwad, Anurag Kaushal, Gautam Mandal +1
We present a microscopic model of black hole (BH) `evaporation' in asymptotically spacetimes dual to the low energy sector of the SYK model. To describe evaporation, the SY…
Gauge Invariant Target Space Entanglement in D-Brane Holography
Sumit R. Das, Anurag Kaushal, Sinong Liu +2
It has been suggested in arXiv:2004.00613 that in Dp-brane holography, entanglement in the target space of the D-brane Yang-Mills theory provides a precise notion of bulk entanglem…
Bulk Entanglement Entropy and Matrices
Sumit R. Das, Anurag Kaushal, Gautam Mandal +1
Motivated by the Bekenstein Hawking formula and the area law behaviour of entanglement entropy, we propose that in any UV finite theory of quantum gravity with a smooth spacetime,…
Quantum quench and thermalization to GGE in arbitrary dimensions and the odd-even effect
Parijat Banerjee, Adwait Gaikwad, Anurag Kaushal +1
In many quantum quench experiments involving cold atom systems the post-quench system can be described by a quantum field theory of free scalars or fermions, typically in a box or…
