Renyi divergences from Euclidean quenches
Barsha G. Chowdhury, Shouvik Datta, Justin R. David
We study the generalisation of relative entropy, the Renyi divergence in 2 CFTs between an excited state density matrix , created by deforming the Hamiltonia…
Semi-classical Virasoro blocks: proof of exponentiation
Mert Besken, Shouvik Datta, Per Kraus
Virasoro conformal blocks are expected to exponentiate in the limit of large central charge and large operator dimensions , with the ratios held fixed. We prove th…
Phase Coherent Oscillations of Excitonic Photocapacitance and Bose-Einstein Condensation in Quantum Coupled 0D-2D Heterostructure
Amit Bhunia, Mohit Kumar Singh, Maryam Al Huwayz +2
We report quantum coherent oscillations of photocapacitance of a double-barrier resonant tunneling heterostructure with bias at 10 K. Periodic presence and absence of sharp exciton…
Quantum thermalization and Virasoro symmetry
Mert Besken, Shouvik Datta, Per Kraus
We initiate a systematic study of high energy matrix elements of local operators in 2d CFT. Knowledge of these is required in order to determine whether the eigenstate thermalizati…
Typicality and thermality in 2d CFT
Shouvik Datta, Per Kraus, Ben Michel
We identify typical high energy eigenstates in two-dimensional conformal field theories at finite and establish that correlation functions of the stress tensor in such states a…
Sphere partition functions and cut-off AdS
Pawel Caputa, Shouvik Datta, Vasudev Shyam
We consider sphere partition functions of TT deformed large N conformal field theories in d=2,3,4,5 and 6 dimensions, computed using the flow equation. These are shown to non-pertu…
