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. |
