Holographic boundary actions in AdS/CFT revisited
Kevin Nguyen
The generating functional of stress tensor correlation functions in two-dimensional conformal field theory is the nonlocal Polyakov action, or equivalently, the Liouville or Alekse…

Celestial IR divergences and the effective action of supertranslation modes
Kevin Nguyen, Jakob Salzer
Infrared divergences in perturbative gravitational scattering amplitudes have been recently argued to be governed by the two-point function of the supertranslation Goldstone mode o…

Reparametrization modes in 2d CFT and the effective theory of stress tensor exchanges
Kevin Nguyen
We study the origin of the recently proposed effective theory of stress tensor exchanges based on reparametrization modes, that has been used to efficiently compute Virasoro identi…
