Soft Heisenberg Hair
  OKC/Nordita High-Energy Physics Theory seminar

Monday 03 April 2017
from 13:15 to 14:14
at Nordita East Building ( 132:028 )
Speaker : Daniel Grumiller (Vienna University of Technology)
Abstract : "Soft hair" refers to zero energy excitations in the near horizon region of black holes or cosmologies, advocated by Hawking, Perry and Strominger. I review recent results on soft hair in 3 spacetime dimensions. The near horizon symmetry algebra is surprisingly simple, namely infinite copies of the Heisenberg algebra. The results are fairly universal and allow a semi-classical construction of microstates for BTZ black holes, whose degeneracy correctly accounts for their Bekenstein-Hawking entropy.
