Asymptotic Symmetries and Charges in De Sitter Space
Dionysios Anninos, Gim Seng Ng, Andrew Strominger
The asymptotic symmetry group (ASG) at future null infinity (I^+) of four-dimensional de Sitter spacetimes is defined and shown to be given by the group of three-dimensional diffeo…
Holography and the Coleman-Mermin-Wagner theorem
Dionysios Anninos, Sean A. Hartnoll, Nabil Iqbal
In 2+1 dimensions at finite temperature, spontaneous symmetry breaking of global symmetries is precluded by large thermal fluctuations of the order parameter. The holographic corre…
The Curious Case of Null Warped Space
Dionysios Anninos, Geoffrey Compère, Sophie de Buyl +2
We initiate a comprehensive study of a set of solutions of topologically massive gravity known as null warped anti-de Sitter spacetimes. These are pp-wave extensions of three-dimen…
A de Sitter Hoedown
Dionysios Anninos, Tarek Anous
Rotating black holes in de Sitter space are known to have interesting limits where the temperatures of the black hole and cosmological horizon are equal. We give a complete descrip…
