M Theory Model of a Big Crunch/Big Bang Transition (2004)
Turok, Neil, Perry, Malcolm, Steinhardt, Paul J.
We consider a picture in which the transition from a big crunch to a big bang corresponds to the collision of two empty orbifold planes approaching each other at a constant non-relativistic speed in...
Spacetime-varying couplings and Lorentz violation (2002)
Kostelecky, Alan, Lehnert, Ralf, Perry, Malcolm
Spacetime-varying coupling constants can be associated with violations of local Lorentz invariance and CPT symmetry. An analytical supergravity cosmology with time-varying fine-structure constant...
Brane Splitting via Quantum Tunneling (2001)
We study the two-centred AdS_7 x S^4 solution of eleven-dimensional supergravity using the Euclidean path-integral approach, and find that it can be interpreted as an instanton, signalling the...

Off-shell structure of the string sigma model (1999)
Kostelecky, Alan, Perry, Malcolm, Potting, Robertus
The off-shell structure of the string sigma model is investigated. In the open bosonic string, nonperturbative effects are shown to depend crucially on the regularization scheme. A scheme retaining...

Interacting Chiral Gauge Fields in Six Dimensions and Born-Infeld Theory (1996)
Perry, Malcolm, Schwarz, John H.
Dimensional reduction of a self-dual tensor gauge field in 6d gives an Abelian vector gauge field in 5d. We derive the conditions under which an interacting 5d theory of an Abelian vector gauge field...
Solitonic Black Holes in Gauged N=2 Supergravity (1995)
Kostelecky, Alan, Perry, Malcolm
A sequence of zero-temperature black-hole spacetimes with angular momentum and electric and magnetic charges is shown to exist in gauged $N=2$ supergravity. Stability of a subset of these spacetimes...
Tachyon Hair for Two-Dimensional Black Holes (1993)
Kostelecky, Alan, Perry, Malcolm
Using a combination of analytical and numerical methods, we obtain a two-dimensional spacetime describing a black hole with tachyon hair. The physical ADM mass of the black hole is finite. The...
Condensates and Singularities in String Theory (1993)
Kostelecky, Alan, Perry, Malcolm
We derive a class of solutions to the string sigma-model equations for the closed bosonic string. The tachyon field is taken to form a constant condensate and the beta-function equations at one-loop...
Path Intergals and Perturbative Expansions for Non-Compact Symmetric Spaces (1992)
We show how to construct path integrals for quantum mechanical systems where the space of configurations is a general non-compact symmetric space. Associated with this path integral is a perturbation...
