Hidden singularities and closed timelike curves in a proposed dual for Lifshitz-Chern-Simons gauge theories
arXiv:1112.0578 · doi:10.1103/PhysRevD.85.121902
Abstract
We point out that the metrics recently proposed by K. Balasubramanian and J. McGreevy \cite{BalaMcGreevyLifshitz} as gravitational duals to Lifshitz Chern-Simons gauge theories contain both a hidden null singularity and a region of closed timelike curves accessible to asymptotic observers. Like the singularity in the original Liftshitz spacetime given by Kachru, Liu, and Mulligan, this singularity does not include large or corrections and hence appears to be singular in string theory as well as classically.
