Gravity Dual of a Quantum Hall Plateau Transition
Joshua L. Davis, Per Kraus, Akhil Shah
We show how to model the transition between distinct quantum Hall plateaus in terms of D-branes in string theory. A low energy theory of 2+1 dimensional fermions is obtained by con…
String Theory Effects on Five-Dimensional Black Hole Physics
Alejandra Castro, Joshua L. Davis, Per Kraus +1
We review recent developments in understanding quantum/string corrections to BPS black holes and strings in five-dimensional supergravity. These objects are solutions to the effect…
Stringy NJL and Gross-Neveu models at finite density and temperature
Joshua L. Davis, Michael Gutperle, Per Kraus +1
Nonlocal stringy versions of the Nambu-Jona-Lasinio and Gross-Neveu models arise in a certain limit of holographic QCD. We analyze the phase structure at finite density and tempera…
Integrable Deformations of Strings in Flux Backgrounds
Joshua L. Davis, Finn Larsen, Ross O'Connell +1
We study d=2 0A string theory perturbed by tachyon momentum modes in backgrounds with non-trivial tachyon condensate and Ramond-Ramond (RR) flux. In the matrix model description, w…
The Moduli Space and Phase Structure of Heterotic Strings in Two Dimensions
Joshua L. Davis
We explore the moduli space of heterotic strings in two dimensions. In doing so, we introduce new lines of compactified theories with Spin(24) gauge symmetry and discuss compactifi…
Heterotic Strings in Two Dimensions and New Stringy Phase Transitions
Joshua L. Davis, Finn Larsen, Nathan Seiberg
We discuss heterotic string theories in two dimensions with gauge groups Spin(24) and Spin(8) x E_8. After compactification the theories exhibit a rich spectrum of states with both…
