Mass of Dyonic Black Holes and Entropy Super-Additivity
Wei-Jian Geng, Blake Giant, H. Lu +1
We study extremal static dyonic black holes in four-dimensional Einstein-Maxwell-Dilaton theory, for general values of the constant in the exponential coupling of the…

BPS Kerr-AdS Time Machines
M. Cvetic, Wei-Jian Geng, H. Lu +1
It was recently observed that Kerr-AdS metrics with negative mass describe smooth spacetimes that have a region with naked closed time-like curves, bounded by a velocity of light s…

Godel Metrics with Chronology Protection in Horndeski Gravities
Wei-Jian Geng, Shou-Long Li, H. Lu +1
Gödel universe, one of the most interesting exact solutions predicted by General Relativity, describes a homogeneous rotating universe containing naked closed time-like curves (CTC…
