Description
Ever since the observation of Bekenstein that not only black hole mechanics can be given the form of the laws of thermodynamics, with area of horizon playing the role of
entropy, the surface gravity of temperature and the mass of the black hole as energy, the study of black hole thermodynamics has been a very active area of research due to fundamental problems posed by such a connection. Hawking’s discovery that black holes actually radiate via thermal spectrum gives credence to the idea that the connection between geometry and thermodynamical quantities is not incidental, rather reveals the underlying deep quantum structure of space-time as the entropy associated with a single classical solution must have a microscopic origin in more fundamental degrees of freedom.
Summary
We study quantum corrections to the entropy of certain black hole solutions in
Horava’s gravity which is a promising proposal for describing the ultra-violet behav-
ior of General Relativity. It is found that unlike in classical GR, the entropy formula
is drastically changed through quantum corrections in the Horava’s gravity by terms
that are proportional to inverse of the horizon area.
