Non - critical bosonic string corrections to the black hole entropy
نویسندگان
چکیده
We calculate the quantum corrections to the entropy of a very large black hole, coming from the theory of a D-dimensional, non-critical bosonic string. We show that, for D > 2, as a result of modular invariance the entropy is ultraviolet finite, although it diverges in the infrared (while for D = 2 the entropy contains both ultraviolet and infrared divergences). The issue of modular invariance in field theory, in connection with black-hole entropy, is also investigated.

The phase transition of corrected black hole with f(R) gravity
In this letter, we consider static black hole in f(R) gravity.We take advantage from corrected entropy and temperature and investigate such black hole. Finally, we study the $ P - V $ critically and phase transition of corrected black hole with respect to entropy and temperature. Here also, we obtain the heat capacity for the static black hole in $ f(R) $ gravity. This calculation help us...
متن کاملString Theory
We review basic aspects as well as recent developments in string theory. We discuss the correspondence between superstring theory on curved spaces and gauge theories in flat space-time, the computation of gluon scattering amplitudes using a topological string and the relation between four-dimensional supersymmetric gauge theories and bosonic matrix models. We consider non-critical strings and t...
متن کاملOn free energy of 2-d black hole in bosonic string theory
Trying to interpret recent matrix model results (hep-th/0101011) we discuss computation of classical free energy of exact dilatonic 2-d black hole from the effective action of string theory. The euclidean space-time action evaluated on the black hole background is divergent due to linear dilaton vacuum contribution, and its finite part depends on a subtraction procedure. The thermodynamic appro...
متن کاملSubleading Contributions from Instanton Corrections in N = 2 Supersymmetric Black Hole Entropy
We present subleading corrections to the N = 2 supersymmetric black hole entropy. These subleading contributions correspond to instanton corrections of the Type II string theory. In particular we consider an axion free black hole solution of low-energy effective Type II string theory. We present a procedure to include successiv all instanton corrections. Expanding these corrections at particula...
متن کاملDyon Spectrum in N = 4 Supersymmetric Type II String Theories
We compute the spectrum of quarter BPS dyons in freely acting ZZ2 and ZZ3 orbifolds of type II string theory compactified on a six dimensional torus. For large charges the result for statistical entropy computed from the degeneracy formula agrees with the corresponding black hole entropy to first non-leading order after taking into account corrections due to the curvature squared terms in the e...
