Dilaton and off-shell (non-critical string) effects in Boltzmann equation for species abundances
A. B. Lahanas, N. E. Mavromatos, D. V. Nanopoulos
In this work we derive the modifications to the Boltzmann equation governing the cosmic evolution of relic abundances induced by dilaton dissipative-source and non-critical-string…
CPT and Quantum Mechanics Tests with Kaons
Jose Bernabeu, John Ellis, Nick E. Mavromatos +2
In this review we first discuss the theoretical motivations for possible CPT violation and deviations from ordinary quantum-mechanical behavior of field-theoretic systems in the co…
The issue of Dark Energy in String Theory
Nick E. Mavromatos
Recent astrophysical observations, pertaining to either high-redshift supernovae or cosmic microwave background temperature fluctuations, as those measured recently by the WMAP sat…
Decoherence induced CPT violation and entangled neutral mesons
J. Bernabeu, Nick E. Mavromatos, Sarben Sarkar
We discuss two classes of semi-microscopic theoretical models of stochastic space-time foam in quantum gravity and the associated effects on entangled states of neutral mesons, sig…
Methods of approaching decoherence in the flavour sector due to space-time foam
N. E. Mavromatos, Sarben Sarkar
In the first part of this work we discuss possible effects of stochastic space-time foam configurations of quantum gravity on the propagation of ``flavoured'' (Klein-Gordon and Dir…
Dissipative Liouville Cosmology: A Case Study
G. A. Diamandis, B. C. Georgalas, A. B. Lahanas +2
We consider solutions of the cosmological equations pertaining to a dissipative, dilaton-driven off-equilibrium Liouville Cosmological model, which may describe the effective field…
