Cosmic Censorship in Lorentz Violating Theories of Gravity
Michael Meiers, Mehdi Saravani, Niayesh Afshordi
Is Cosmic Censorship special to General Relativity, or can it survive a violation of equivalence principle? Recent studies have shown that singularities in Lorentz violating Einste…
Spacetime Curvature in terms of Scalar Field Propagators
Mehdi Saravani, Siavash Aslanbeigi, Achim Kempf
We show how quantum fields can be used to measure the curvature of spacetime. In particular, we find that knowledge of the imprint that spacetime curvature leaves in the correlator…
A Stueckelberg Approach to Quadratic Curvature Gravity and its Decoupling Limits
Kurt Hinterbichler, Mehdi Saravani
Curvature squared terms, when added to the Einstein-Hilbert action and treated non-perturbatively, generically result in the propagation of an extra massive scalar state and an ext…
Dark Matter From Spacetime Nonlocality
Mehdi Saravani, Siavash Aslanbeigi
We propose that dark matter is not yet another new particle in nature, but that it is a remnant of quantum gravitational effects on known fields. We arrive at this possibility in a…
