Life on a closed timelike curve

open access: yesClassical and Quantum Gravity
Abstract We study the internal dynamics of a hypothetical spaceship traveling on a close timelike curve in an axially symmetric Universe. We choose the curve so that the generator of evolution in proper time is the angular momentum. Using Wigner’s theorem, we prove that the energy levels internal to the spaceship must undergo spontaneous

Scalar instabilities inside the extremal dyonic Kerr–Sen black hole: novel exact solutions and Chronology Protection Conjecture

open access: yesEuropean Physical Journal C: Particles and Fields
We investigate the stability of test scalar fields in the region inside the extremal dyonic Kerr–Sen black hole (DKSBH) horizon, where closed timelike curves exist.
