Photon Production From The Scattering of Axions Out of a Solenoidal Magnetic Field (2009)
Guendelman, Eduardo I., Shilon, Idan, Cantatore, Giovanni, Zioutas, Konstantin
In this paper we calculate the total cross section for the production of photons from the scattering of axions by a strong inhomogeneous magnetic field in the form of a 2D delta function, a...
Instability of Axions and Photons In The Presence of Cosmic Strings (2008)
Guendelman, Eduardo I., Shilon, Idan
We report that axions and photons exhibit instability in the presence of cosmic strings that are carrying magnetic flux in their core. The strength of the instability is determined by the symmetry...
Axions and Photons In Terms of "Particles" and "Anti-Particles" (2008)
Guendelman, Eduardo I., Shilon, Idan
The axion photon system in an external magnetic field, when for example considered with the geometry of the experiments exploring axion photon mixing (which can be represented by a 1+1 effective...
Stabilization of Neutral Thin Shells By Gravitational Effects From Electric Fields (2008)
Guendelman, Eduardo I., Shilon, Idan
We study the properties of a system consisting of an uncharged spherically symmetric two dimensional extended object which encloses a stationary point charge placed in the shell's center. We show...
Ansoldi, Stefano, Guendelman, Eduardo I., Shilon, Idan
We present a review of selected topics concerning the creation and evolution of child universes, together with a concise account of some recent progress in the field.
Gravitational Trapping Near Domain Walls and Stable Solitons (2006)
Guendelman, Eduardo, Shilon, Idan
In this work, the behavior of test particles near a domain wall of a stable false vacuum bubble is studied. It is shown that matter is naturally trapped in the vicinity of a static domain wall, and...
