Modular crossings, OPE coefficients and black holes
Diptarka Das, Shouvik Datta, Sridip Pal
In (1+1)-d CFTs, the 4-point function on the plane can be mapped to the pillow geometry and thereby crossing symmetry gets translated into a modular property. We use these modular…
Monstrous entanglement
Diptarka Das, Shouvik Datta, Sridip Pal
The Monster CFT plays an important role in moonshine and is also conjectured to be the holographic dual to pure gravity in AdS3. We investigate the entanglement and Renyi entropies…
Charged structure constants from modularity
Diptarka Das, Shouvik Datta, Sridip Pal
We derive a universal formula for the average heavy-heavy-light structure constants for 2d CFTs with non-vanishing u(1) charge. The derivation utilizes the modular properties of on…
An exactly solvable quench protocol for integrable spin models
Diptarka Das, Sumit R. Das, Damián A. Galante +2
Quantum quenches in continuum field theory across critical points are known to display different scaling behaviours in different regimes of the quench rate. We extend these results…
On thermality of CFT eigenstates
Pallab Basu, Diptarka Das, Shouvik Datta +1
The Eigenstate Thermalization Hypothesis (ETH) provides a way to understand how an isolated quantum mechanical system can be approximated by a thermal density matrix. We find a cla…
