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.

Trapped string states in AdS5 black hole geometry: a path toward Hawking radiation

Journal of High Energy Physics
We investigate the quantum dynamics of a closed bosonic string in the curved spacetime of an AdS5-Schwarzschild black hole. Starting from the Polyakov action, we perform a canonical quantization of the string and formulate its quantum mechanical equation

Gravitational waves in the Myers-Perry geometry

Journal of High Energy Physics
We analyze equations describing gravitational waves in the Myers-Perry and Gibbons-Lu-Page-Pope geometries with arbitrary rotation parameters. Assuming that at least one rotation parameter vanishes, we demonstrate full separability of equations for ...

On Black Holes In String Theory

, 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.

Black Holes in String Theory

, 1996
This thesis is devoted to trying to find a microscopic quantum description of black holes. We consider black holes in string theory which is a quantum theory of gravity. We find that the ``area law'' black hole entropy for extremal and near-extremal charged black holes arises from counting microscopic configurations.

Locality and causality properties of light cone string field theory [PDF]

, 2004
The recent discovery of a new maximally supersymmetric background for the type IIB superstring theory has revived the interest in light cone string field theory.

Building the blocks of Schwarzschild

Journal of High Energy Physics
We demonstrate that the Schwarzschild black hole can be “resolved” into bound states of Reissner-Nordström black holes in four dimensions. These bound states closely resemble the Schwarzschild geometry from the asymptotic region up to an infinitesimal ...

Black holes and vacua in string theory: A non-supersymmetric study [PDF]

, 2019
During the past few decades, an important part of the understanding of gravity in the context of string theory has relied on gravitational configurations that enjoy supersymmetry. Despite the knowledge retrieved under supersymmetry, we still do not fully

T-duality invariant approaches to string theory [PDF]

, 2010
PhDThis thesis investigates the quantum properties of T-duality invariant formalisms of String Theory. We introduce and review duality invariant formalisms of String Theory including the Doubled Formalism.
