S-Duality at the Black Hole Threshold in Gravitational Collapse
Douglas M. Eardley, Eric W. Hirschmann, James H. Horne
We study gravitational collapse of the axion/dilaton field in classical low energy string theory, at the threshold for black hole formation. A new critical solution is derived that…
Charged Dilaton Black Holes with Unusual Asymptotics
Kevin C. K. Chan, James H. Horne, Robert B. Mann
We present a new class of black hole solutions in Einstein-Maxwell-dilaton gravity in dimensions. These solutions have regular horizons and a singularity only at the orig…
Chaotic Coupling Constants
James H. Horne, Gregory Moore
We examine some novel physical consequences of the general structure of moduli spaces of string vacua. These include (1) finiteness of the volume of the moduli space and (2) chaoti…
Cosmic Censorship and the Dilaton
James H. Horne, Gary T. Horowitz
We investigate extremal electrically charged black holes in Einstein-Maxwell-dilaton theory with a cosmological constant inspired by string theory. These solutions are not static,…
Rotating Dilaton Black Holes
James H. Horne, Gary T. Horowitz
It is shown that an arbitrarily small amount of angular momentum can qualitatively change the properties of extremal charged black holes coupled to a dilaton. In addition, the gyro…
Exact Black String Solutions in Three Dimensions
James H. Horne, Gary T. Horowitz
A family of exact conformal field theories is constructed which describe charged black strings in three dimensions. Unlike previous charged black hole or extended black hole soluti…
