Titre | Symmetry, Soft Dynamics and Holography in Asymptotically Flat Spacetimes |
Résumé | Celestial CFT is a formalism which attempts to recast quantum gravity in (d+2)- dimensional asymptotically flat spacetimes in terms of a d-dimensional Euclidean CFT residing at the conformal boundary. I will discuss certain universal aspects of this correspondence. As in anti-de Sitter space, bulk gravitons produce a boundary stress tensor, and bulk gluons furnish boundary conserved currents. I will also show that continuous spaces of vacua in the bulk map directly onto the conformal manifold of the boundary CFT. This correspondence provides a new perspective on the role of the BMS group in flat space holography, and offers a new interpretation of the antisymmetric double-soft gluon theorem in terms of the curvature of an infinite-dimensional vacuum manifold. |
