Fixing All Moduli in a Simple F-theory Compactification
(International Press, 2005)
We discuss a simple example of an F-theory compactification on a Calabi-Yau fourfold where background fluxes, nonperturbative effects from Euclidean D3 instantons and gauge dynamics on D7 branes allow us to fix all closed ...
Precision Counting of Small Black Holes
(Institute of Physics, 2005)
It has recently been proposed that a class of supersymmetric higher-derivative interactions in Script N = 2 supergravity may encapsulate an infinite number of finite size corrections to the microscopic entropy of certain ...
Exact and Asymptotic Degeneracies of Small Black Holes
(Institute of Physics, 2005)
We examine the recently proposed relations between black hole entropy and the topological string in the context of type II/heterotic string dual models. We consider the degeneracies of perturbative heterotic BPS states. ...
Black Hole Bound States in AdS(3) x S**2
(Institute of Physics, 2008)
We systematically construct the geometries dual to the 1+1 dimensional (0, 4) conformal field theories that arise in the low-energy description of wrapped M5-branes in S<sup>1</sup> × CY<sub>3</sub> compactifications of ...
Physics of String Flux Compactifications
(Annual Reviews, Inc., 2007)
We provide a qualitative review of flux compactifications of string theory, focusing on broad physical implications and statistical methods of analysis.
How Many Black Holes Fit on the Head of a Pin?
(Springer Verlag, 2007)
The Bekenstein–Hawking entropy of certain black holes can be computed microscopically in string theory by mapping the elusive problem of counting microstates of a strongly gravitating black hole to the tractable problem ...
Quantum Oscillations and Black Hole Ringing
(American Physical Society, 2009)
We show that strongly coupled field theories with holographic gravity duals at finite charge density and low temperatures can undergo de Haas–van Alphen quantum oscillations as a function of an external magnetic field. ...
Landscape of Superconducting Membranes
(American Physical Society, 2009)
The AdS/CFT correspondence may connect the landscape of string vacua and the `atomic landscape' of condensed matter physics. We study the stability of a landscape of IR fixed points of N=2 large N gauge theories in 2+1 ...
Statistics of M-theory vacua
(American Institute of Physics, 2005)
We study the vacuum statistics of ensembles of <i>M</i> theory compactifications on G<sub>2</sub> holonomy manifolds with fluxes, and of ensembles of Freund-Rubin vacua. We discuss similarities and differences between these ...
D-brane Deconstructions in IIB Orientifolds
(Institute of Physics, 2009)
With model building applications in mind, we collect and develop basic techniques to analyze the landscape of D7-branes in type IIB compact Calabi-Yau orientifolds, in three different pictures: F-theory, the D7 worldvolume ...
