The Impact of Particle Production on Gravitational Baryogenesis
J. A. S. Lima, Douglas Singleton
Baryogenesis driven by curvature effects is investigated by taking into account gravitationally induced particle production in the very early Universe. In our scenario, the baryon…
Particle production in a gravitational wave background
Preston Jones, Patrick McDougall, Douglas Singleton
We study the possibility that massless particles, such as photons, are produced by a gravitational wave. That such a process should occur is implied by tree-level, Feynman diagrams…
Time dependent electromagnetic fields and 4-dimensional Stokes' theorem
Ryan Andosca, Douglas Singleton
Stokes' theorem is central to many aspects of physics -- electromagnetism, the Aharonov-Bohm effect, and Wilson loops to name a few. However, the pedagogical examples and research…
Compact and extended objects from self-interacting phantom fields
Vladimir Dzhunushaliev, Vladimir Folomeev, Arislan Makhmudov +3
In this work we investigate localized and extended objects for gravitating, self-interacting phantom fields. The phantom fields come from two scalar fields with a "wrong sign" (neg…
Global versus Local -- Mach's Principle versus the Equivalence Principle
Douglas Singleton, Steve Wilburn
The equivalence principle is the conceptual basis for general relativity. In contrast Mach's principle, although said to have been influential on Einstein in his formulation of gen…
