Black Hole Graybody Factor and Black Hole Entropy
نویسنده
چکیده
We have proposed the entropy formula of the black hole which is constructed by two intersecting D-branes with no momentum, whose compactification radii are constrained by the surface gravities in ten-dimensions. We interpret the entropy of the black hole as the statistical entropy of the effective string. We further study the behavior of the absorption cross-section of the black hole using our entropy formula. 04.70.Dy, 04.20.Gz, 04.50.+h Typeset using REVTEX 1

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 کاملOrganizational Black Hole Theory
There are issues in organizations that require new theoretical formulation. Hence, metaphorical theorizing is used in the study of organizations to interpret them and understand their complexities. In this method, the organization is likened to an entity and one of the key features of that entity is generalized to the organization. It should be borne in mind that most organizational theories ar...
متن کاملStretching the Horizon of a Higher Dimensional Small Black Hole
There is a general scaling argument that shows that the entropy of a small black hole, representing a half-BPS excitation of an elementary heterotic string in any dimension, agrees with the statistical entropy up to an overall numerical factor. We propose that for suitable choice of field variables the near horizon geometry of the black hole in D space-time dimensions takes the form of AdS2 × S...
متن کاملImproved Upper Bound to the Entropy of a Charged System. II
Recently, we derived an improved universal upper bound to the entropy of a charged system S ≤ π(2Eb − q2)/h̄. There was, however, some uncertainty in the value of the numerical factor which multiply the q2 term. In this paper we remove this uncertainty; we rederive this upper bound from an application of the generalized second law of thermodynamics to a gedanken experiment in which an entropy-be...
متن کاملOn quantum black hole entropy and Newton constant renormalization
We discuss the status of the black hole entropy formula SBH = AH/4G in low energy effective field theory. The low energy expansion of the black hole entropy is studied in a non-equilibrium situation: the semiclassical decay of hot flat space by black hole nucleation. In this context the entropy can be defined as an enhancement factor in the semiclassical decay rate, which is dominated by a spha...
