Fermat Principle in Finsler Spacetimes
It is shown that, on a manifold with a Finsler metric of Lorentzian signature, the lightlike geodesics satisfy the following variational principle. Among all lightlike curves from a point q (emission event) to a timelike curve γ (worldline of receiver), the lightlike geodesics make the arrival time stationary. Here “arrival time” refers to a parametrization of the timelike curve γ. This variati...
متن کاملBirefringence in pseudo–Finsler spacetimes
Based on the analogue spacetime programme, and many other ideas currently mooted in “quantum gravity”, there is considerable ongoing speculation that the usual pseudoRiemannian (Lorentzian) manifolds of general relativity might eventually be modified at short distances. Two specific modifications that are often advocated are the adoption of Finsler geometries (or more specifically, pseudo-Finsl...
متن کاملDual spacetimes, Mach’s Principle and topological defects
By resolving the Riemann curvature relative to a unit timelike vector into electric and magnetic parts, we define a duality transformation which interchanges active and passive electric parts. It implies interchange of roles of Ricci and Einstein curvatures. Further by modifying the vacuum/flat equation we construct spacetimes dual to the Schwarzschild solution and flat spacetime. The dual spac...
متن کاملFermat Principle for polarized light and the Optical Hall effect
Mimicking the description of spinning particles in General Relativity, the Fermat Principle is extended to polarized photons. Linearization of the resulting Papapetrou-Souriau type equations yields the semiclassical model used recently to derive the “Optical Hall Effect”. The shift of the planes of the incident and refracted (resp. reflected) light found by Onoda, Murakami and Nagaosa is recove...
متن کاملt-PERIODIC LIGHT RAYS IN CONFORMALLY STATIONARY SPACETIMES VIA FINSLER GEOMETRY
In this paper we prove several multiplicity results of t-periodic light rays in conformally stationary spacetimes using the Fermat metric and the extensions of the classical theorems of Gromoll-Meyer and Bangert-Hingston to Finsler manifolds. Moreover, we exhibit some stationary spacetimes with a finite number of t-periodic light rays and compute a lower bound for the period of the light rays w...
