Dark matter and nonlocality of spacetime
Mehdi Saravani
In this letter, we review a candidate for dark matter, known as ODM, and explain how it relates to spacetime nonlocality. This connection provides a physical interpretation for…
Classification of shift-symmetric Horndeski theories and hairy black holes
Mehdi Saravani, Thomas P. Sotiriou
No-hair theorems for scalar-tensor theories imply that the trivial scalar field configuration is the unique configuration around stationary black hole spacetimes. The most basic as…
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…
Causal structure of black holes in shift-symmetric Horndeski theories
Robert Benkel, Nicola Franchini, Mehdi Saravani +1
In theories with derivative (self-)interactions, the propagation of perturbations on nontrivial field configurations is determined by effective metrics. Generalized scalar-tensor t…
Black hole horizons at the extremal limit in Lorentz-violating gravity
Nicola Franchini, Mehdi Saravani, Thomas P. Sotiriou
Lorentz-violating gravity theories with a preferred foliation can have instantaneous propagation. Nonetheless, it has been shown that black holes can still exist in such theories a…
