Landau damping for gravitational waves in parity-violating theories
Flavio Bombacigno, Fabio Moretti, Simon Boudet +1
We discuss how tensor polarizations of gravitational waves can suffer Landau damping in the presence of velocity birefringence, when parity symmetry is explicitly broken. In partic…
Torsional birefringence in metric-affine Chern-Simons gravity: gravitational waves in late-time cosmology
S. Boudet, F. Bombacigno, F. Moretti +1
In the context of the metric-affine Chern-Simons gravity endowed with projective invariance, we derive analytical solutions for torsion and nonmetricity in the homogeneous and isot…
Linear analysis of the gravitational beam-plasma instability
Fabio Moretti, Matteo Del Prete, Giovanni Montani
We investigate the well-known phenomenon of the beam-plasma instability in the gravitational sector, when a fast population of particles interacts with the massive scalar mode of a…
