Black hole horizons at the extremal limit in Lorentz-violating gravity (2017)
Journal Article
Franchini, N., Saravani, M., & Sotiriou, T. P. (2017). Black hole horizons at the extremal limit in Lorentz-violating gravity. Physical Review D, 96(10), Article 104044. https://doi.org/10.1103/PhysRevD.96.104044

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 and the relevant notion of an event horizon has been dubbed “universal...

Off-shell dark matter: a cosmological relic of quantum gravity (2017)
Journal Article
Saravani, M., & Afshordi, N. (2017). Off-shell dark matter: a cosmological relic of quantum gravity. Physical Review D, 95(4), Article 043514. https://doi.org/10.1103/PhysRevD.95.043514

We study a novel proposal for the origin of cosmological cold dark matter (CDM) which is rooted in the quantum nature of spacetime. In this model, off-shell modes of quantum fields can exist in asymptotic states as a result of spacetime nonlocality (...
