Near-horizon symmetries of the Schwarzschild black hole with supertranslation field
Mikhail Z. Iofa
Using the exact solution to Einstein equations of Compere and Long for the Schwarzschild metric containing supertranslation field, we study the near-horizon symmetries of the metri…
Thermal Hawking radiation of black hole with supertranslation field
Mikhail Z. Iofa
Using the analytical solution for the Schwarzschild metric containing supertranslation field, we consider two main ingredients of calculation of the thermal Hawking black hole radi…
Energy-momentum tensor of bouncing gravitons
Mikhail Z. Iofa
In models of the Universe with extra dimensions gravity propagates in the whole space-time. Graviton production by matter on the brane is significant in the early hot Universe. In…
Microscopic entropy of trapping horizon
Mikhail Z. Iofa
In the Carlip-Majhi-Padmanabhan approach, we calculate microscopic entropy of trapping (apparent) horizon of the FRW metric. We solve Killing equations for part of the metric…
Contribution of bouncing gravitons to the energy-momentum tensor
Mikhail Z. Iofa
In a model of 3-brane with matter embedded in 5D space-time conditions for gravitons emitted from the brane to the bulk to return back to the brane are found. A method to calculate…
Bouncing of gravitons emitted from the brane to the bulk back to the brane
Mikhail Z. Iofa
Solutions of geodesic equations describing propagation of gravitons in the bulk are studied in a cosmological model with one extra dimension. Brane with matter is embedded in the b…
Connection between two forms of extra-dimensional metrics revisited
Mikhail Z. Iofa
5D cosmological model with 3-brane with matter is considered. The brane divides bulk in two AdS half spaces. Geometry of the model can be described by two types of coordinates: in…
Near-horizon behavior of string-loop-corrected dyonic black holes
Mikhail Z. Iofa
Dyonic black holes with string-loop corrections are studied in the near-horizon region. In perturbative heterotic string theory compactified to four dimensions with N=2 supersymmet…

Mikhail Z. Iofa
In heterotic string theory compactified to four dimensions with N=2 supersymmetry, string-loop corrections to the universal sector of the low-energy effective action are studied. W…

Mikhail Z. Iofa
We discuss the form of the string-loop-corrected effective action obtained by compactification of the heterotic string theory on the manifold or on its orbifold limi…
N=2 Supersymmetry and String-Loop Corrected Magnetic Black Holes
Mikhail Z. Iofa
We study string-loop corrections to magnetic black hole. Four-dimensional theory is obtained by compactification of the heterotic string theory on the manifold or on…
String-Loop Corrections Versus Non-Extremality
Mikhail Z. Iofa, Leopoldo A. Pando Zayas
We discuss a magnetic black-hole solution to the equations of motion of the string-loop-corrected effective action. At the string-tree level, this solution is the extremal magnetic…
Statistical Entropy of Calabi-Yau Black Holes
Mikhail Z. Iofa, Leopoldo A. Pando Zayas
We computed the statistical entropy of nonextremal 4D and extremal 5D Calabi-Yau black holes and found exact agreement with the Bekenstein-Hawking entropy. The computation is based…
Statistical Entropy of Magnetic Black Holes from Near--Horizon Geometry
Mikhail Z. Iofa, Leopoldo A. Pando Zayas
Four-dimensional magnetic black holes including dilaton and abelian gauge fields which are solutions of supergravity can also be obtained by dimensional reduction of the Einstein-M…

Mikhail Z. Iofa, Leopoldo A. Pando Zayas
We discuss charged black-hole solutions to the equations of motion of the string-loop-corrected effective action. At the string-tree level, these solutions provide backgrounds for…
Nonabelian Fields in Exact String Solutions
M. Z. Iofa, and L. A. Pando Zayas
Within the framework of "anomalously gauged" Wess-Zumino-Witten (WZW) models, we construct solutions which include nonabelian fields. Both compact and noncompact groups are discuss…

M. Z. Iofa
One-string-loop (torus topology) corrections to black-string backgrounds corresponding to gauged WZW model are calculated using -function equations derived…
