The recent confirmation that at least some γ-ray bursts originate at cosmological distances suggests that the radiation from them could be used to probe some of the fundamental laws of physics. Here…

This white paper addresses the hypothesis of light sterile neutrinos based on recent anomalies observed in neutrino experiments and the latest astrophysical data.
Potential Sensitivity of Gamma-Ray Burster Observations to Wave Dispersion in Vacuo
- G. Amelino-Camelia, J. Ellis, N. Mavromatos, D. Nanopoulos, S. Sarkar
- Physics
- 7 December 1997
The recent confirmation that at least some gamma-ray bursters (GRBs) are indeed at cosmological distances raises the possibility that observations of these could provide interesting constraints on…
Quantum-gravity analysis of gamma-ray bursts using wavelets
- J. Ellis, N. Mavromatos, D. Nanopoulos, A. Sakharov
- Physics
- 4 October 2002
In some models of quantum gravity, space-time is thought to have a foamy structure with non-trivial optical prop- erties. We probe the possibility that photons propagating in vacuum may exhibit a…

Distance Measurement and Wave Dispersion in a Liouville-String Approach to Quantum Gravity
- G. Amelino-Camelia, J. Ellis, N. Mavromatos, D. Nanopoulos
- Physics
- 29 May 1996
Within a Liouville approach to noncritical string theory, we discuss space–time foam effects on the propagation of low-energy particles. We find an induced frequency-dependent dispersion in the…
Light-by-Light Scattering Constraint on Born-Infeld Theory.

- PhysicsPhysical Review Letters
- 24 March 2017
The recent measurement by ATLAS of light-by-light scattering in LHC Pb-Pb collisions is the first direct evidence for this basic process. We find that it excludes a range of the mass scale of a…
QED-cavity model of microtubules implies dissipationless energy transfer and biological quantum teleportation
- N. Mavromatos, A. Mershin, D. Nanopoulos
- Physics
- 4 April 2002
We refine a QED-cavity model of microtubules (MTs), proposed earlier by two of the authors (N.E.M. and D.V.N.), and suggest mechanisms for the formation of biomolecular mesoscopic coherent and/or…
