Black Hole Entropy in Induced Gravity: Reduction to 2D Quantum Field Theory on the Horizon
It is argued that degrees of freedom responsible for the Bekenstein-Hawking
entropy of a black hole in induced gravity are described by two dimensional
quantum field theory defined on the bifurcation surface of the horizon. This
result is proved for a class of induced gravity models with scalar, spinor and
vector heavy constituents.Comment: 19 pages, latex, no figure
Thermodynamics of string black hole with hyperscaling violation
In this paper, we start with black brane and construct specific space-time
which violates hyperscaling. In order to obtain the string solution we apply
Null-Melvin-Twist and -reduction. By using the difference action method we
study thermodynamics of system to obtain Hawking-Page phase transition. In
order to have hyperscaling violation we need to consider
In that case the free energy is always negative and our solution is thermal
radiation without a black hole. Therefore we find that there is not any
Hawking-Page transition. Also, we discuss the stability of system and all
thermodynamical quantities.Comment: 12 pages. Accepted for publication in EPJ
