SUMMARY:Holographic Thermodynamics of Accelerating Black Holes - Ruth Greg

DESCRIPTION:One of the more curious exact solutions of Einstein gravity is
  the "C-metric"\, a metric representing an accelerating black hole\, the f
 orce being provided by a cosmic string emerging from the black hole horizo
 n. The black hole is neither isolated\, nor static\, unless we embed it in
  AdS and drop the acceleration below the AdS scale - a so called "slowly a
 ccelerating black hole". I will describe how to derive thermodynamics for 
 the non-isolated black hole\, including the cosmic string tension as a the
 rmodynamical variable -- as a result\, a new chemical potential is introdu
 ced\, the thermodynamic length. I will also discuss a set of extensive var
 iables\, or chemical expressions for the black hole that do not involve an
 y reference to the geometrical parameters and describe some critical pheno
 mena for the black hole.
