Flavour Condensates in Brane Models and Dark Energy
Nick E. Mavromatos, Sarben Sarkar, Walter Tarantino
In the context of a microscopic model of string-inspired foam, in which foamy structures are provided by brany point-like defects (D-particles) in space-time, we discuss flavour mi…
Incompatibility of Rotation Curves with Gravitational Lensing for TeVeS
Ignacio Ferreras, Nick E. Mavromatos, Mairi Sakellariadou +1
We constrain the one-parameter class of TeVeS models by testing the theory against both rotation curve and strong gravitational lensing data on galactic scales, remaining fully rel…
CPT Violation and Decoherence in Quantum Gravity
Nick E. Mavromatos
In this brief review I discuss ways and tests of CPT-Violation in the context of quantum gravity theories with space-time foam vacua, which entail quantum decoherence of matter pro…
Exploration of Possible Quantum Gravity Effects with Neutrinos I: Decoherence in Neutrino Oscillations Experiments
Alexander Sakharov, Nick Mavromatos, Anselmo Meregaglia +2
Quantum gravity may involve models with stochastic fluctuations of the associated metric field, around some fixed background value. Such stochastic models of gravity may induce dec…
Time Delays of Strings in D-particle Backgrounds and Vacuum Refractive Indices
Tianjun Li, Nick E. Mavromatos, Dimitri V. Nanopoulos +1
Using standard techniques in string/D-brane scattering amplitude computations, we evaluate the scattering of open strings off D-particles in brane world scenarios. The D-particles…
