Simplified Vacuum Energy Expressions for Radial Backgrounds and Domain Walls

Gerald Dunne, Klaus Kirsten

We extend our previous results of simplified expressions for functional determinants for radial Schrödinger operators to the computation of vacuum energy, or mass corrections, for…

Colliding branes and formation of spacetime singularities in string theory

Andreas Tziolas, Anzhong Wang, Zhong Chao Wu

Colliding branes without symmetry and the formation of spacetime singularities in string theory are studied. After developing the general formulas to describe such events,…

Casimir Energy and Brane Stability

Richard Obousy, Gerald Cleaver

We investigate the role of Casimir energy as a mechanism for brane stability in five-dimensional models with the fifth dimension compactified on an S^1\Z_2 orbifold, which includes…

Comment on: "The Casimir force on a piston in the spacetime with extra compactified dimensions" [Phys. Lett. B 668 (2008) 72]

S. A. Fulling, K. Kirsten

We offer a clarification of the significance of the indicated paper of H. Cheng. Cheng's conclusions about the attractive nature of Casimir forces between parallel plates are valid…

Brane cosmology in the Horava-Witten heterotic M-Theory on

Qiang Wu, Yungui Gong, Anzhong Wang

We study the radion stability and radion mass in the framework of the Horava-Witten (HW) heterotic M-Theory on , and find that the radion is stable and its mass can be…

Free Fermionic Heterotic Model Building and Root Systems

M. Robinson, G. Cleaver, M. Hunziker

We consider an alternative derivation of the GSO Projection in the free fermionic construction of the weakly coupled heterotic string in terms of root systems, as well as the inter…

Elliptic aspects of statistical mechanics on spheres

J. S. Dowker, Klaus Kirsten

Our earlier results on the temperature inversion properties and the ellipticisation of the finite temperature internal energy on odd spheres are extended to orbifold factors of odd…

Vacuum Stress and Closed Paths in Rectangles, Pistons, and Pistols

S. A. Fulling, L. Kaplan, K. Kirsten +2

Rectangular cavities are solvable models that nevertheless touch on many of the controversial or mysterious aspects of the vacuum energy of quantum fields. This paper is a thorough…

Quasi-realistic heterotic-string models with vanishing one-loop cosmological constant and perturbatively broken supersymmetry?

Gerald B. Cleaver, Alon E. Faraggi, Elisa Manno +1

Quasi-realistic string models in the free fermionic formulation typically contain an anomalous U(1), which gives rise to a Fayet-Iliopoulos D-term that breaks supersymmetry at the…
