Hamiltonian Dynamics of Cosmological Quintessence Models
Rossen I. Ivanov, Emil M. Prodanov
The time-evolution dynamics of two nonlinear cosmological real gas models has been reexamined in detail with methods from the theory of Hamiltonian dynamical systems. These example…
Daemon Decay and Inflation
Emil M. Prodanov
Quantum tunneling in Reissner-Nordstrom geometry is studied and the tunneling rate is determined. A possible scenario for cosmic inflation, followed by reheating phases and subsequ…
Equation of State for a van der Waals Universe during Reissner-Nordstrom Expansion
Emil M. Prodanov, Rossen I. Ivanov, V. G. Gueorguiev
In a previous work [E.M. Prodanov, R.I. Ivanov, and V.G. Gueorguiev, Reissner-Nordstrom Expansion, Astroparticle Physics 27 (150-154) 2007], we proposed a classical model for the e…
Reissner-Nordstrom Expansion
Emil M. Prodanov, Rossen I. Ivanov, V. G. Gueorguiev
We propose a classical mechanism for the cosmic expansion during the radiation-dominated era. This mechanism assumes that the Universe is a two-component gas. The first component i…
Haunted Kaluza Universe with Four-dimensional Lorentzian Flat, Kerr, and Taub-NUT Slices
Rossen I. Ivanov, Emil M. Prodanov
The duality between the original Kaluza's theory and Klein's subsequent modification is duality between slicing and threading decomposition of the five-dimensional spacetime. The f…
Riemann Tensor of the Ambient Universe, the Dilaton and the Newton's Constant
Rossen I. Ivanov, Emil M. Prodanov
We investigate a four-dimensional world, embedded into a five-dimensional spacetime, and find the five-dimensional Riemann tensor via generalisation of the Gauss (--Codacci) equati…
On the Field Equations of Kaluza's Theory
Rossen I. Ivanov, Emil M. Prodanov
The field equations of the original Kaluza's theory are analyzed and it is shown that they lead to modification of Einstein's equations. The appearing extra energy-momentum tensor…
Bouncing Branes
Emil M. Prodanov
Two classical scalar fields are minimally coupled to gravity in the Kachru-Shulz-Silverstein scenario with a rolling fifth radius. A Tolman wormhole solution is found for a R x S^3…
Standard Cosmology on a Self-Tuning Domain Wall
Conall Kennedy, Emil M. Prodanov
We investigate the cosmology of (4+1)-dimensional gravity coupled to a scalar field and a bulk anisotropic fluid within the context of the single-brane Randall-Sundrum scenario. As…
A remark on Schwarz's topological field theory
David H. Adams, Emil M. Prodanov
The standard evaluation of the partition function of Schwarz's topological field theory results in the Ray--Singer analytic torsion. Here we present an alternative evaluation w…
Standard Cosmology from Sigma-Model
Conall Kennedy, Emil M. Prodanov
We investigate (4+1)- and (5+0)-dimensional gravity coupled to a non-compact scalar field sigma-model and a perfect fluid within the context of the Randall-Sundrum scenario. We fin…
Abelian Duality
Emil M. Prodanov, Siddhartha Sen
We show that on three-dimensional Riemannian manifolds without boundaries and with trivial first real de Rham cohomology group (and in no other dimensions) scalar field theory and…
On the Absence of Cross-Confinement for Dynamically Generated Multi-Chern-Simons Theories
Emil M. Prodanov, Siddhartha Sen
We show that when the induced parity breaking part of the effective action for the low-momentum region of U(1) x ... x U(1) Maxwell gauge field theory with massive fermions in 3 di…
Equivalence of the Self-Dual Model and Maxwell-Chern-Simons Theory on Arbitrary Manifolds
Emil M. Prodanov, Siddhartha Sen
Using a group-invariant version of the Faddeev-Popov method we explicitly obtain the partition functions of the Self-Dual Model and Maxwell-Chern-Simons theory. We show that their…
