A Lanczos approach to the Adiabatic Gauge Potential
Budhaditya Bhattacharjee
The Adiabatic Gauge Potential (AGP) is the generator of adiabatic deformations between quantum eigenstates. There are many ways to construct the AGP operator and evaluate the AGP n…
HKLL for the Non-Normalizable Mode
Budhaditya Bhattacharjee, Chethan Krishnan, Debajyoti Sarkar
We discuss various aspects of HKLL bulk reconstruction for the free scalar field in AdS. First, we consider the spacelike reconstruction kernel for the non-normalizable mod…
Celestial Klein Spaces
Budhaditya Bhattacharjee, Chethan Krishnan
We consider the analytic continuation of -dimensional Minkowski space (with and even) to -signature, and study the conformal boundary of the resulting "Klein…
A General Prescription for Semi-Classical Holography
Budhaditya Bhattacharjee, Chethan Krishnan
We present a version of holographic correspondence where bulk solutions with sources localized on the holographic screen are the key objects of interest, and not bulk solutions def…
Brans-Dicke wormholes in the Jordan and Einstein frames
K. K. Nandi, B. Bhattacharjee, S. M. K. Alam +1
We examine the possibility of static wormhole solutions in the vacuum Brans-Dicke theory both in the original (Jordan) frame and in the conformally rescaled (Einstein) frame. It tu…
