3D Stress Tensor for Gravity in 4D Flat Spacetime
Arjun Bagchi, Prateksh Dhivakar, Sudipta Dutta
Three dimensional (3d) Carrollian CFTs are potential co-dimension one holographic duals of 4d asymptotically flat spacetimes that live on the whole of the null boundary. In this pa…
Holography in Flat Spacetimes: the case for Carroll
Arjun Bagchi, Prateksh Dhivakar, Sudipta Dutta
We compare and contrast the two approaches of holography in asymptotically flat spacetimes, viz. the co-dimension two Celestial approach based on the Mellin transformation and the…
AdS Witten Diagrams to Carrollian Correlators
Arjun Bagchi, Prateksh Dhivakar, Sudipta Dutta
Carrollian Conformal Field Theories (CFTs) have been proposed as co-dimension one holographic duals to asymptotically flat spacetimes as opposed to Celestial CFTs which are co-dime…
