ADHMN boundary conditions from removing monopoles

Xingang Chen, Erick J. Weinberg

Boundary conditions play an important role in the ADHMN construction of BPS monopole solutions. In this paper we show how different types of boundary conditions can be related to e…

Evidence for a gravitational Myers effect

Jan de Boer, Eric Gimon, Koenraad Schalm +1

An indication for the existence of a collective Myers solution in the non-abelian D0-brane Born-Infeld action is the presence of a tachyonic mode in fluctuations around the standar…

Supergravity, Supermembrane and M(atrix) model on PP-Waves

Norihiro Iizuka

In the first part of this paper, we study the back-reaction of large-N light cone momentum on the maximally supersymmetric anti-pp-wave background. This gives the type IIA geometry…

Brane gas cosmology in M-theory: late time behavior

Richard Easther, Brian R. Greene, Mark G. Jackson +1

We investigate the late-time behavior of a universe containing a supergravity gas and wrapped 2-branes in the context of M-theory compactified on T^10. The supergravity gas tends t…

Massless monopole clouds and electric-magnetic duality

Xingang Chen

We discuss the Montonen-Olive electric-magnetic duality for the BPS massless monopole clouds in N=4 supersymmetric Yang-Mills theory with non-Abelian unbroken gauge symmetries. We…

Elliptic de Sitter Space: dS/Z_2

Maulik K. Parikh, Ivo Savonije, Erik Verlinde

We propose that for every event in de Sitter space, there is a CPT-conjugate event at its antipode. Such an ``elliptic'' -identification of de Sitter space provides a concrete…

A Quantum Mechanical Model of Spherical Supermembranes

John Conley, Ben Geller, Mark G. Jackson +2

We present a quantum mechanical model of spherical supermembranes. Using superfields to represent the cartesian coordinates of the membrane, we are able to exactly determine its su…

A "Periodic Table" for Supersymmetric M-Theory Compactifications

Charles F. Doran, Michael Faux

We develop a systematic method for classifying supersymmetric orbifold compactifications of M-theory. By restricting our attention to abelian orbifolds with low order, in the speci…

On the Hagedorn Behaviour of PP-wave Strings and N=4 SYM Theory at Finite R-Charge Density

Brian R. Greene, Koenraad Schalm, Gary Shiu

We discuss the high temperature behaviour of IIB strings in the maximally symmetric plane wave background, and show that there is a Hagedorn temperature. We discuss the map between…

Intersecting Branes in M-Theory and Chiral Matter in Four Dimensions

Charles F. Doran, Michael Faux

We explicitly derive a complementary pair of four-dimensional M-theory brane-world models, linked by a five-dimensional bulk, each of which has a unique anomaly-free chiral spectru…

Quantum Field Theory and Representation Theory: A Sketch

Peter Woit

A sketch is given of a circle of ideas relating quantum field theories with representation theory. The main mathematical ingredients are spinor geometry and the gauge group equivar…

Quantum Quivers and Hall/Hole Halos

Frederik Denef

Two pictures of BPS bound states in Calabi-Yau compactifications of type II string theory exist, one as a set of particles at equilibrium separations from each other, the other as…

de Sitter entropy from conformal field theory

Daniel Kabat, Gilad Lifschytz

We propose that the entropy of de Sitter space can be identified with the mutual entropy of a dual conformal field theory. We argue that unitary time evolution in de Sitter space r…

A generic estimate of trans-Planckian modifications to the primordial power spectrum in inflation

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

We derive a general expression for the power spectra of scalar and tensor fluctuations generated during inflation given an arbitrary choice of boundary condition for the mode funct…

New Coordinates for de Sitter Space and de Sitter Radiation

Maulik K. Parikh

We introduce a simple coordinate system covering half of de Sitter space. The new coordinates have several attractive properties: the time direction is a Killing vector, the metric…

Cosmological String Gas on Orbifolds

Richard Easther, Brian R. Greene, Mark G. Jackson

It has long been known that strings wound around incontractible cycles can play a vital role in cosmology. In particular, in a spacetime with toroidal spatial hypersurfaces, the dy…

Elliptic Families of Solutions of the Kadomtsev-Petviashvili Equation and the Field Elliptic Calogero-Moser System

A. Akhmetshin, I. Krichever, Yu. Volvovski

We present the Lax pair for the field elliptic Calogero-Moser system and establish a connection between this system and the Kadomtsev-Petviashvili equation. Namely, we consider ell…

On the Graviton Self Energy in AdS_4

Massimo Porrati, Andrei Starinets

We consider Einstein gravity coupled to a CFT made of a single free conformal scalar in 4-d Anti de Sitter space. This simple case is rich enough to explain an unexpected gravitati…
