EXTREME DYONIC BLACK HOLES IN STRING THEORY [PDF]
Modern Physics Letters A, 1996 Supersymmetric extreme dyonic black holes of toroidally compactified heterotic or type-II string theory can be viewed as lower-dimensional images of solitonic strings wound around a compact dimension. We consider conformal sigma models which describe string configurations corresponding to various extreme dyonic black holes in four and five dimensions.

Remark on black hole entropy in string theory [PDF]
Physical Review D, 1994 We extend the string-theoretic calculation of black hole entropy, first performed by Susskind and Uglum, away from the infinite mass limit. It is shown that the result agrees with that obtained from the classical action of string theory, using the Noether charge method developed by Wald.

Black holes in supergravity and string theory [PDF]
Classical and Quantum Gravity, 2000 We give an elementary introduction to black holes in supergravity and string theory. The focus is on BPS solutions in four- and higher-dimensional supergravity and string theory. Basic ideas and techniques are explained in detail, including exercises with solutions.

α′-corrected black holes in String Theory [PDF]
Journal of High Energy Physics, 2018 Abstract We consider the well-known solution of the Heterotic Superstring effective action to zeroth order in α ′ that describes the intersection of a fundamental string with momentum and a solitonic 5-brane and which gives a 3-charge, static, extremal, supersymmetric black hole in 5 dimensions upon dimensional ...

BLACK HOLE GEOMETRIES IN NONCOMMUTATIVE STRING THEORY [PDF]
International Journal of Modern Physics A, 2006 We obtain a generalized Schwarzschild (GS) and a generalized Reissner–Nordstrom (GRN) black hole geometries in 3+1 dimensions, in a noncommutative string theory. In particular, we consider an effective theory of gravity on a curved D3-brane in presence of an electromagnetic (EM) field.

On Black Holes In String Theory [PDF]
, 1991 In these lecture notes from Strings `91, I briefly sketch the analogy between two dimensional black holes and the s-wave sector of four dimensional black holes, and the physical interest of the latter, particularly in the magnetically charged case.

A stringy glimpse into the black hole horizon
Journal of High Energy Physics, 2018 We elaborate on the recent claim [1] that non-perturbative effects in α′, which are at the core of the FZZ duality, render the region just behind the horizon of the SL(2, ℝ) k /U(1) black hole singular already at the classical level (g s = 0).

Three-Charge Black Holes and Quarter BPS States in Little String Theory [PDF]
, 2015 We show that the system of $k$ NS5-branes wrapping $\mathbb{T}^4\times S^1$ has non-trivial vacuum structure. Different vacua have different spectra of 1/4 BPS states that carry momentum and winding around the $S^1$.
