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…
BMS modular covariance and structure constants
Arjun Bagchi, Saikat Mondal, Sanchari Pal +1
Two-dimensional (2d) field theories invariant under the Bondi-Metzner-Sachs algebra, or 2d BMSFTs in short, are putative holographic duals of Einstein gravity in 3d asymptotically…
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…
Carrollian Origins of Bjorken Flow
Arjun Bagchi, Kedar S. Kolekar, Ashish Shukla
Bjorken flow is among the simplest models of fluids moving near the speed of light () while Carroll symmetry arises as a contraction of Poincaré group when . We show th…
Non-Lorentzian Kač-Moody Algebras
Arjun Bagchi, Ritankar Chatterjee, Rishabh Kaushik +2
We investigate two dimensional (2d) quantum field theories which exhibit Non- Lorentzian Kač-Moody (NLKM) algebras as their underlying symmetry. Our investigations encompass both 2…
