Dirac equation in exotic spacetimes

2020-01-16T12:54:28+01:00Tags: , |

Authors: Faba Garcia, Javier; Sabin, Carlos Contribution: Article Journal: PHYSICAL REVIEW D Publication date: 2019/01/14 DOI: 10.1103/PhysRevD.99.025008 Abstract: We find solutions of the Dirac equation in curved spacetime. In particular, we consider 1 + 1 dimensional sections of several exotic metrics: the Alcubierre metric, which describes a scenario that allows faster-than-light velocity; the Godel metric, which [...]
