f(R)-Gravity: "Einstein Frame" Lagrangian Formulation, Non-Standard Black Holes and QCD-like Confinement/Deconfinement
Eduardo Guendelman, Alexander Kaganovich, Emil Nissimov +1
We consider f(R) = R + R^2 gravity interacting with a dilaton and a special non-standard form of nonlinear electrodynamics containing a square-root of ordinary Maxwell Lagrangian.…
Dynamical Volume Element in Scale-Invariant and Supergravity Theories
Eduardo Guendelman, Emil Nissimov, Svetlana Pacheva +1
The use in the action integral of a volume element of the form , where is a metric-independent measure density, can yield new interesting results in all types of known…
Dynamical Couplings and Charge Confinement/Deconfinement from Gravity Coupled to Nonlinear Gauge Fields
Eduardo Guendelman, Alexander Kaganovich, Emil Nissimov +1
We briefly outline several main results concerning various new physically relevant features found in gravity -- both ordinary Einstein or gravity in the first-order fo…
Lightlike Membranes in Black Hole and Wormhole Physics, and Cosmology
Eduardo Guendelman, Alexander Kaganovich, Emil Nissimov +1
We shortly outline the principal results concerning the reparametrization-invariant world-volume Lagrangian formulation of lightlike brane dynamics and its impact as a source for g…
Charge-Confining Gravitational Electrovacuum Shock Wave
Eduardo Guendelman, Emil Nissimov, Svetlana Pacheva
In previous publications we have extensively studied spherically symmetric solutions of gravity coupled to a non-standard type of non-linear electrodynamics containing a square roo…
