Gravitational birefringence of light in Schwarzschild spacetime
Christian Duval, Loic Marsot, Thomas Schucker
We compute the gravitational birefringence of light as it undergoes gravitational lensing. To this end we re-derive the Souriau-Saturnini equations in the Schwarzschild metric and…
Gravitational birefringence of light at cosmological scales
Christian Duval, Thomas Schucker
Birefringence of light induced not by matter, but by the gradient of an electric field, has been predicted in 1955 and observed in 2008. Here we replace the electric field by the g…
Gravitational birefringence and an exotic formula for redshift
Christian Duval, Johanna Pasquet, Thomas Schucker +1
We compute the birefringence of light in curved Robertson-Walker spacetimes and propose an exotic formula for redshift based on the internal structure of the spinning photon. We th…
Velocity Memory Effect for Polarized Gravitational Waves
P. -M. Zhang, C. Duval, G. W. Gibbons +1
Circularly polarized gravitational sandwich waves exhibit, as do their linearly polarized counterparts, the Velocity Memory Effect: freely falling test particles in the flat after-…
Memory Effect for Impulsive Gravitational Waves
P. -M. Zhang, C. Duval, P. A. Horvathy
Impulsive gravitational plane waves, which have a delta-function singularity on a hypersurface, can be obtained by squeezing smooth plane gravitational waves with Gaussian profile.…
The Memory Effect for Plane Gravitational Waves
P. M. Zhang, C. Duval, G. W. Gibbons +1
We give an account of the gravitational memory effect in the presence of the exact plane wave solution of Einstein's vacuum equations. This allows an elementary but exact descripti…
