The (super)conformal BMS algebra
Oscar Fuentealba, Hernan A. Gonzalez, Alfredo Perez +2
The conformal extension of the BMS algebra is constructed. Apart from an infinite number of 'superdilatations,' in order to incorporate 'superspecial conformal transformation…
Loops on the Celestial Sphere
Hernan A. Gonzalez, Andrea Puhm, Francisco Rojas
We study the effect of loop corrections to conformal correlators on the celestial sphere at null infinity. We first analyze finite one-loop celestial amplitudes in pure Yang-Mills…
Flat space holography and complex SYK
Hamid Afshar, Hernan Gonzalez, Daniel Grumiller +1
We provide the first steps towards a flat space holographic correspondence in two bulk spacetime dimensions. The gravity side is described by a conformally transformed version of t…
New entropy formula for Kerr black holes
Hernan Gonzalez, Daniel Grumiller, Wout Merbis +1
We introduce a new entropy formula for Kerr black holes inspired by recent results for 3-dimensional black holes and cosmologies with soft Heisenberg hair. We show that also Kerr-T…
Geometric actions for three-dimensional gravity
Glenn Barnich, Hernan A. Gonzalez, Patricio Salgado-Rebolledo
The solution space of three-dimensional asymptotically anti-de Sitter or flat Einstein gravity is given by the coadjoint representation of two copies of the Virasoro group in the f…
BMS Modules in Three Dimensions
Andrea Campoleoni, Hernan A. Gonzalez, Blagoje Oblak +1
We build unitary representations of the BMS algebra and its higher-spin extensions in three dimensions, using induced representations as a guide. Our prescription naturally emerges…
