Physical Consequences of a Theory with Dynamical Volume Element
E. I. Guendelman, A. B. Kaganovich
We survey motivation, basic ideas and physical consequences of a theory where the underlying action involves terms both with the usual volume element and with the…
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…
Cosmic Analogues of the Stern-Gerlach Experiment and the Detection of Light Bosons
Doron Chelouche, Eduardo I. Guendelman
We show that, by studying the arrival times of radio pulses from highly-magnetized pulsars, it may be possible to detect light spin-0 bosons (such as axions and axion-like particle…
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…
Stabilization of Neutral Thin Shells By Gravitational Effects From Electric Fields
Eduardo I. Guendelman, Idan Shilon
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…
The universe out of a breathing bubble
Eduardo I. Guendelman, Nobuyuki Sakai
We consider the model of a false vacuum bubble with a thin wall where the surface energy density is composed of two different components, "domain-wall" type and "dust" type, with o…
Transition to Zero Cosmological Constant and Phantom Dark Energy as Solutions Involving Change of Orientation of Space-Time Manifold
E. I. Guendelman, A. B. Kaganovich
Solutions with degenerate metric ( or ) in the first order formalism (FOF) are physically acceptable: they may describe topology changes (Horowitz) and red…
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…
