Entanglement and squeezing of gravitational waves
Thiago Guerreiro
We show that the self-interactions present in the effective field theory formulation of general relativity can couple gravitational wave modes and generate nonclassical states. The…

Nonlinear Ringdowns as Sources and Detectors of Quantum Gravitational Waves
Thiago Guerreiro
Is gravity quantum mechanical? If so, we argue that nonlinear effects in black hole ringdowns - notably second harmonic generation - generates gravitational waves in non-classical…
