Axion Photon Oscillations From a "Particle-Antiparticle" View Point
E. I. Guendelman
We observe that it is very usefull to introduce a complex field for the axion photon system in an external magnetic field, when for example considered with the geometry of the expe…
Continuous Axion Photon Duality and its Consequences
E. I. Guendelman
The axion photon system in an external magnetic field, when for example considered with the geometry of the experiments exploring axion photon mixing, displays a continuous axion-p…
Stability, Singularities and Mass Thresholds in Child Universe Production: a concise survey including some recent results and prospects
Stefano Ansoldi, Eduardo I. Guendelman, Idan Shilon
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.
Lightlike Braneworlds
Eduardo Guendelman, Alexander Kaganovich, Emil Nissimov +1
We propose a new class of p-brane models describing intrinsically lightlike branes in any world-volume dimensions. Properties of the dynamics of these lightlike p-branes in various…
"Mass Inflation" With Lightlike Branes
Eduardo Guendelman, Alexander Kaganovich, Emil Nissimov +1
We discuss properties of a new class of p-brane models, describing intrinsically lightlike branes for any world-volume dimension, in various gravitational backgrounds of interest i…
No axions in light shinning through a wall experiments
J. Gamboa, E. I. Guendelman, F. Mendez
This paper has been withdrawn and a new version will be submitted soon
Symmetry Supporting a Transition to Zero Cosmological Constant State
E. I. Guendelman, A. B. Kaganovich
In a number of previous publications we demonstrated that the Two Measures Field Theory (TMT) enables to resolve the old cosmological constant (CC) problem avoiding the Weinberg's…
Universes out of almost empty space
Stefano Ansoldi, Eduardo I. Guendelman
Baby universes (inflationary or non--inflationary) are regions of spacetime that disconnect from the original ambient spacetime, which we take to be asymptotically flat spacetime.…
Absence of the Fifth Force Problem in a Model with Spontaneously Broken Dilatation Symmetry
E. I. Guendelman, A. B. Kaganovich
A scale invariant model containing dilaton and dust (as a model of matter) is studied where the shift symmetry is spontaneously broken at the classical level due…
Strong Interaction Dynamics from Spontaneous Symmetry Breaking of Scale Invariance
E. I. Guendelman
Using the mechanism of spontaneous symmetry breaking of scale invariance obtained from the dynamics of maximal rank field strengths, it is possible to spontaneously generate confin…
Child universes UV regularization?
E. I. Guendelman
It is argued that high energy density excitations, responsible for UV divergences in quantum field theories, including quantum gravity, are likely to be the source of child univers…
Initial Singularity, Lambda-Problem and Crossing the Phantom Divide in Scale Invariant TMT Model
E. I. Guendelman, A. B. Kaganovich
In the framework of the scale invariant model of the Two Measures Field Theory (TMT), we study the dilaton-gravity sector in the context of spatially flat FRW cosmology. The scale…
Generalized Gauge Field Approach To Lightlike Branes
E. I. Guendelman, A. Kaganovich, E. Nissimov +1
We propose a general action describing the dynamics of lightlike (LL) p-branes in any odd (p+1) world-volume dimensions. Next, we consider self-consistent coupling of \textsl{LL}-m…
Static potential from spontaneous breaking of scale symmetry
Patricio Gaete, Eduardo Guendelman, Euro Spallucci
We determine the static potential for a heavy quark-antiquark pair from the spontaneous symmetry breaking of scale invariance in a non-Abelian gauge theory. Our calculation is done…
