Casimir Effect for Nonlocal Field Theories with Continuum Massive Modes
Mehdi Saravani
In this paper, we study the Casimir force for a class of Lorentzian nonlocal field theories. These theories include a continuum of massive excitations. In this regard, the effect o…
Continuum Modes of Nonlocal Field Theories
Mehdi Saravani
A class of nonlocal Lorentzian quantum field theories is introduced in arXiv:1502.01655 and arXiv:1411.6513, where the d'Alembertian operator is replaced by a non-analytic f…
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…
On the Causal Set-Continuum Correspondence
Mehdi Saravani, Siavash Aslanbeigi
We present two results which concern certain aspects of the question: when is a causal set well approximated by a Lorentzian manifold? The first result is a theorem which shows tha…
Generalized Causal Set d'Alembertians
Siavash Aslanbeigi, Mehdi Saravani, Rafael D. Sorkin
We introduce a family of generalized d'Alembertian operators in D-dimensional Minkowski spacetimes which are manifestly Lorentz-invariant, retarded, and non-local, the extent of th…
Spacetime Entanglement Entropy in 1+1 Dimensions
Mehdi Saravani, Rafael D. Sorkin, Yasaman K. Yazdi
arXiv:1205.2953 defines an entropy for a gaussian scalar field in an arbitrary region of either a causal set or a continuous spacetime, given only the correlator $\langleϕ(x)ϕ(…
Empty Black Holes, Firewalls, and the Origin of Bekenstein-Hawking Entropy
Mehdi Saravani, Niayesh Afshordi, Robert B. Mann
We propose a novel solution for the endpoint of gravitational collapse, in which spacetime ends (and is orbifolded) at a microscopic distance from black hole event horizons. This m…
