Black Holes in String Theory

, 2019
Black holes are the hydrogen atoms of quantum gravity. For instance solving the information loss paradox will likely require a deep understanding of how the long-sought quantum gravity theory works. In this thesis we explore how black holes are modelled and how the quantum structure emerges in the context of string theory.

Can One Understand Black Hole Entropy without Knowing Much about Quantum Gravity? [PDF]

, 2004
It is a common belief now that the explanation of the microscopic origin of the Bekenstein-Hawking entropy of black holes should be available in quantum gravity theory, whatever this theory will finally look like.

Massless radiation from heavy rotating string and Kerr/string correspondence

, 2009
We calculate emission rates of a massless state from a highly excited rotating string in perturbative bosonic open string theory. By averaging huge degeneracies of initial string states with specifying the mass and a single component of the angular ...

On the Microscopic Perspective of Black Branes Thermodynamic Geometry

Entropy, 2010
We study thermodynamic state-space geometry of the black holes in string theory and M-theory. For a large number of microstates, we analyze the intrinsic state-space geometry for (i) extremal and non-extremal black branes in string theory, (ii) multi ...

Revisiting logarithmic correction to five dimensional BPS black hole entropy

Journal of High Energy Physics
We compute logarithmic correction to the entropy of BPS black holes in asymptotically flat five dimensional space-time using finite temperature black hole geometry and find perfect agreement with the microscopic results and macroscopic computations based

Five-dimensional black holes in heterotic string theory

, 2007
We review recent results on near-horizon static black hole solutions and entropy in R^2-corrected N=2 SUGRA in D=5, focusing on actions connected to heterotic string compactified on K3\times S^1.

Size and shape of rotating strings and the correspondence to black holes

Journal of High Energy Physics
In light of the correspondence between black holes and fundamental strings with non-zero spin, we compute the sizes of rotating strings for small, moderate, and large values of the angular momentum and compare them to the sizes of rotating black holes ...

Rotating Einstein-Maxwell black holes in odd dimensions

Journal of High Energy Physics
To construct higher-dimensional counterparts of the Kerr-Newman black holes, we consider Einstein’s equations sourced by a vector field and a negative cosmological constant.

State-Space Geometry, Statistical Fluctuations, and Black Holes in String Theory

Advances in High Energy Physics, 2014
We study the state-space geometry of various extremal and nonextremal black holes in string theory. From the notion of the intrinsic geometry, we offer a state-space perspective to the black hole vacuum fluctuations.

Black holes and solitons in string theory

, 1995
In this review I discuss various aspects of some of the recently constructed black hole and soliton solutions in string theory. I begin with the axionic instanton and related solutions of bosonic and heterotic string theory. The latter ten-dimensional solutions can be compactified to supersymmetric monopole, string and domain wall solutions which break
