Two-Loop Superstrings IV, The Cosmological Constant and Modular Forms

Eric D'Hoker, D. H. Phong

The slice-independent gauge-fixed superstring chiral measure in genus 2 derived in the earlier papers of this series for each spin structure is evaluated explicitly in terms of the…

Two-Loop Superstrings III, Slice Independence and Absence of Ambiguities

Eric D'Hoker, D. H. Phong

The chiral superstring measure constructed in the earlier papers of this series for general gravitino slices is examined in detail for slices supported at two points x_α. In this c…

Imprints of Short Distance Physics On Inflationary Cosmology

Richard Easther, Brian R. Greene, William H. Kinney +1

We analyze the impact of certain modifications to short distance physics on the inflationary perturbation spectrum. For the specific case of power-law inflation, we find distinctiv…

Vector bundles and Lax equations on algebraic curves

Igor Krichever

The Hamiltonian theory of zero-curvature equations with spectral parameter on an arbitrary compact Riemann surface is constructed. It is shown that the equations can be seen as com…

Massless monopoles and the moduli space approximation

Xingang Chen, Huidong Guo, Erick J. Weinberg

We investigate the applicability of the moduli space approximation in theories with unbroken non-Abelian gauge symmetries. Such theories have massless magnetic monopoles that are m…

Probing black holes in non-perturbative gauge theory

Norihiro Iizuka, Daniel Kabat, Gilad Lifschytz +1

We use a 0-brane to probe a ten-dimensional near-extremal black hole with N units of 0-brane charge. We work directly in the dual strongly-coupled quantum mechanics, using mean-fie…

A thermal instability for positive brane cosmological constant in the Randall-Sundrum cosmologies

Stephon Alexander, Yi Ling, Lee Smolin

We describe a novel dynamical mechanism to radiate away a positive four dimensional cosmological constant, in the Randall-Sundrum cosmological scenario. We show that there are mode…

Scattering of massless and massive monopoles in an SU(N) theory

Xingang Chen, Erick J. Weinberg

We use the moduli space approximation to study the time evolution of magnetically charged configurations in a theory with an SU(N+2) gauge symmetry spontaneously broken to U(1) x S…

Inflation as a Probe of Short Distance Physics

Richard Easther, Brian R. Greene, William H. Kinney +1

We show that a string-inspired Planck scale modification of general relativity can have observable cosmological effects. Specifically, we present a complete analysis of the inflati…

Mirror Symmetry in 2+1 and 1+1 Dimensions

Mina Aganagic, Kentaro Hori, Andreas Karch +1

We study the Coulomb-Higgs duality of N=2 supersymmetric Abelian Chern-Simons theories in 2+1 dimensions, by compactifying dual pairs on a circle of radius R and comparing the resu…

Black hole entropy from non-perturbative gauge theory

Daniel Kabat, Gilad Lifschytz, David A. Lowe

We present the details of a mean-field approximation scheme for the quantum mechanics of N D0-branes at finite temperature. The approximation can be applied at strong 't Hooft coup…
