The Effectiveness of D-branes in the Description of Near-Extremal Black Holes
نویسنده
چکیده
It is known that weak coupling calculations of absorption or emission by slightly non-extremal D-brane configurations are in exact agreement with semiclassical results for the black holes they describe at strong couplings. We investigate one open string loop corrections to processes involving single D-branes and show that a class of relevant terms vanish, indicating that these processes are not renormalized. Our results have implications for five dimensional black holes and extremal 3-branes.

D-branes and Near Extremal Black Holes at Low Energies
It has been observed recently that many properties of some near extremal black holes can be described in terms of bound states of D-branes. Using a non-renormalization theorem we argue that the D-brane description is the correct quantum gravity description of the black hole at low energies. The low energy theory includes the black hole degrees of freedom that account for the entropy and describ...
متن کاملBlack holes and D-branes
Black holes have an entropy proportional to the area of the horizon. The microscopic degrees of freedom that give rise to the entropy are not visible in the classical theory. String theory, a quantum theory of gravity, provides a microscopic quantum description of the thermodynamic properties of some extremal and near extremal charged black holes. The description uses properties of some string ...
متن کاملCharged black holes from near extremal black holes
We recover the properties of a wide class of far from extremal charged black branes from properties of near extremal black branes, generalizing the results of Danielsson, Guijosa and Kruczenski.
متن کاملEffective spatial dimension of extremal non-dilatonic black p-branes and the description of entropy on the world volume
By investigating the critical behavior appearing at the extremal limit of the non-dilatonic, black p-branes in (d+ p) dimensions, we find that some critical exponents related to the critical point obey the scaling laws. From the scaling laws we obtain that the effective spatial dimension of the non-dilatonic black holes and black strings is one, and is p for the non-dilatonic black p-branes. Fo...
متن کاملEmission of charged particles from four- and five-dimensional black holes
Recently Das and Mathur found that the leading order Hawking emission rate of neutral scalars by near-extremal D = 5 black holes is exactly reproduced by a string theoretic model involving intersecting D-branes. We show that the agreement continues to hold for charged scalar emission. We further show that similar agreement can be obtained for a class of near-extremal D = 4 black holes using a m...
