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 (…
On the relation between Unruh and Sokolov--Ternov effects
Emil T. Akhmedov, Douglas Singleton
We show that the Sokolov--Ternov effect -- the depolarization of particles in storage rings coming from synchrotron radiation due to spin flip transitions -- is physically equivale…
Electric S-brane solutions with a parallel charge density form on a Ricci-flat factor space
I. S. Goncharenko, V. D. Ivashchuk, S. Rudametkin-Aguilar +1
We generalize the previously studied cosmological solutions in D-dimensional gravity with an antisymmetric (p+2)-form to the case when the spatial part of the metric is Ricci-flat…
No Unruh-like Radiation for circular motion

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…
