Liouville Cosmology
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
Liouville string theory is a natural framework for discussing the non-equilibrium evolution of the Universe. It enables non-critical strings to be treated in mathematically consist…
Impact of Low-Energy Constraints on Lorentz Violation
J. Ellis, E. Gravanis, N. E. Mavromatos +1
We extend previous analyses of the violation of Lorentz invariance induced in a non-critical string model of quantum space-time foam, discussing the propagation of low-energy parti…
Is Nothing Sacred? Vacuum Energy, Supersymmetry and Lorentz Breaking from Recoiling D branes
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
Classical superstring vacua have zero vacuum energy and are supersymmetric and Lorentz-invariant. We argue that all these properties may be destroyed when quantum aspects of the in…
Probing Models of Quantum Space-Time Foam
John Ellis, N. E. Mavromatos, D. V. Nanopoulos
We review the possibility that quantum fluctuations in the structure of space-time at the Planck scale might be subject to experimental probes. We study the effects of space-time f…
