Lightlike Brane as a Gravitational Source of Misner-Wheeler-Type Wormhole
Eduardo Guendelman, Alexander Kaganovich, Emil Nissimov +1
Consistent Lagrangian description of lightlike p-branes (LL-branes) is presented in two equivalent forms - a Polyakov-type formulation and a dual to it Nambu-Goto-type formulation.…
Lightlike p-Branes: Mass "Inflation" and Lightlike Braneworlds
Eduardo Guendelman, Alexander Kaganovich, Emil Nissimov +1
Lagrangian description of lightlike p-branes is presented in two equivalent forms - a Polyakov-type formulation and a dual to it Nambu-Goto-type formulation. Next, the properties o…
Instability of Axions and Photons In The Presence of Cosmic Strings
Eduardo I. Guendelman, Idan Shilon
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…
Axions and Photons In Terms of "Particles" and "Anti-Particles"
Eduardo I. Guendelman, Idan Shilon
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…
Photon and Axion Splitting in an Inhomogeneous Magnetic Field
E. I. Guendelman
The axion photon system in an external magnetic field, when the direction of propagation of axions and photons is orthogonal to the direction of the external magnetic field, displa…
Localized Axion Photon States in a Strong Magnetic Field
E. I. Guendelman
We consider the axion field and electromagnetic waves with rapid time dependence, coupled to a strong time independent, asymptotically approaching a constant at infinity "mean" mag…
