A note on Strong Cosmic Censorship and its violation in Reissner-Nordström de Sitter black hole space-times

Anna Chrysostomou, Alan S Cornell, Aldo Deandrea, Seong Chan Park

Penrose's Strong Cosmic Censorship conjecture safeguards determinism in General Relativity. Within the initial value approach to General Relativity, proof of Strong Cosmic Censorship preservation is predicated on the unique evolution of the metric. For the Kerr-Newman family of black hole…

Quasinormal frequencies in Reissner-Nordström de Sitter black holes: constraints from space-time and scalar field parameters

Anna Chrysostomou, Alan S Cornell, Aldo Deandrea, Seong Chan Park

We examine the quasinormal modes exhibited by a massive scalar test field carrying an electric charge, oscillating in the outer region of a Reissner-Nordström de Sitter black hole. We examine the quasinormal mode effective potential throughout the black hole mass-charge phase space, finding a…

Two Micron-Size Dark Dimensions

Luis Anchordoqui, Ignatios Antoniadis, Dieter Lust

Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In our paper we examine various observational bounds in scenarios with one and two large extra dimensions, to see if they are compatible with the micron scale. We show that consistency…

Are there minimal exceptional aGUTs from stable 5D orbifolds?

Giacomo Cacciapaglia, Alan S Cornell, Aldo Deandrea, Wanda Isnard, Roman Pasechnik, Anca Preda, Zhi-Wei Wang

In analysing five dimensional orbifolds with exceptional gauge groups, we seek to find stable vacua configurations which satisfy the minimal requirements for asymptotic grand unified models. In this respect we show that no minimal asymptotic grand unified theory can be built. Our results point…
