Electric S-brane solutions with parallel forms on Ricci-flat factor space
V. D. Ivashchuk, V. N. Melnikov, D. Singleton
In this paper we generalize electric S-brane solutions with maximal number of branes. Previously for the action containing D-dimensional gravity, a scalar field and antisymmetric (…

Thermal radiation of various gravitational backgrounds
Emil T. Akhmedov, Valeria Akhmedova, Terry Pilling +1
We present a simple and general procedure for calculating the thermal radiation coming from any stationary metric. The physical picture is that the radiation arises as the quasi--c…
Phantom energy from graded algebras
Max Chaves, Douglas Singleton
We construct a model of phantom energy using the graded Lie algebra SU(2/1). The negative kinetic energy of the phantom field emerges naturally from the graded Lie algebra, resulti…
Fermion generations, masses and mixings in a 6D brane model
Silvestre Aguilar, Douglas Singleton
We study the motion of higher dimensional fermions in a non-singular 6D brane background with an increasing warp factor. This background acts as a potential well trapping fermions…
