New Sources of Gravitational Radiation: The Black Hole Graviton Laser

Event Start:

Event Information:

Black holes admit quantum mechanical bound states of ultra light particles such axions or neutrinos.  These states can undergo quantum transitions absorbing or emitting gravitons. Graviton trajectories, in the particle picture, in principle can correspond to gravitons that orbit the black hole arbitrarily many times before finally escaping to infinity. Quantum mechanically, such graviton trajectories correspond to graviton-black hole scattering states which exhibit an arbitrarily large time delay before they emerge at infinity.
