Cascading DGP
Claudia de Rham, Gia Dvali, Stefan Hofmann +4
We present a higher codimension generalization of the DGP scenario which, unlike previous attempts, is free of ghost instabilities. The 4D propagator is made regular by embedding o…
Black Hole Bound on the Number of Species and Quantum Gravity at LHC
Gia Dvali, Michele Redi
In theories with a large number N of particle species, black hole physics imposes an upper bound on the mass of the species equal to M_{Planck}/\sqrt{N}. This bound suggests a nove…
Expanding F-Theory
Matthew Kleban, Michele Redi
We construct a general class of new time dependent solutions of non-linear sigma models coupled to gravity. These solutions describe configurations of expanding or contracting codi…
Consistent Lorentz Violation in Flat and Curved Space
Gia Dvali, Oriol Pujolas, Michele Redi
Motivated by the severity of the bounds on Lorentz violation in the presence of ordinary gravity, we study frameworks in which Lorentz violation does not affect the spacetime geome…
