Cauchy Horizons, Thermodynamics, and Closed Timelike Curves in Planar Supersymmetric Spaces

Abstract
We study geodesically complete, singularity free space-times induced by planar domain walls interpolating between supersymmetric Minkowski (M4) and anti-de Sitter (AdS4) space-times. A geodesically complete space-time with [without] closed timelike curves includes a finite [infinite] number of semi-infinite M4 regions, separated by a region of AdS4. The space-times are nonsingular and exhibit Cauchy horizons with zero Hawking temperature and vanishing entropy.
