In the gravitational sector, we study the CPT violation and birefringence of gravitational waves. In presence of the CPT violation, a relative dephasing is generated between two circular polarization states of gravitational waves. This effect induces the birefringence of gravitational waves. We predict the gravitational waveform corrected by it and estimate the expected constraints on it from Advanced Laser Interferometer Gravitational-Wave Observatory, Einstein Telescope and Laser Interferometer Space Antenna.

  1. Covariant diffusion and drift of the stochastic GW background with LISA

    gr-qc 2025-05 conditional novelty 7.0 of 10

    A Fisher forecast shows LISA could bound graviton diffusion/drift parameters κ1, κ2 down to about 10^-56 kg m^2 s^-3, improving CMB bounds by 12 orders of magnitude, if a phase-transition or PBH background is detected.

  2. Hawking area law in quantum gravity

    gr-qc 2026-04 unverdicted novelty 5.0 of 10

    If Hawking's area law is taken as exact, nonlocal and Stelle quantum-gravity theories are forced to drop R^2 and (Riemann)^2 terms (or use singular Ricci-flat black holes), and the standard entropy-area law follows as...
