Aspects of the bulk flat space limit in AdS/CFT
David Berenstein, Joan Simon
The flat space limit of scalar bulk fields in AdS is discussed within a Lorentzian canonical quantization setup tailored to describe AdS state preparation and to extract the flat S…
Universal sectors of two-dimensional Carrollian CFTs
Ankit Aggarwal, Arjun Bagchi, Stephane Detournay +3
We revisit modular invariance in two-dimensional Carrollian conformal field theories from a geometric perspective. Focusing on the characters of the induced and highest-weight repr…
Modular matrices of 2d Carrollian and warped CFTs
Ankit Aggarwal, Joan Simón
We derive the modular S and T matrices that generate the modular transformations on the characters of two dimensional Carrollian and warped CFT algebras. We verify that they satisf…
BMS fermionic localization
Joan Simón, Boyang Yu
We consider the geometric action formulation for 3d pure gravity with vanishing cosmological constant. We use fermionic localization to compute the exact torus partition function f…
