Gravitationally induced interference of gravitational waves by a rotating massive object - art. no. 083001

We discuss an interesting effect induced by the rotation of a massive objec t acting as a lens for coherent gravitational radiation. We show that the r esult is a concentric interference pattern which is shifted due to the effe ct of thr angular momentum on the phase of radiation, an effect analogous t o the Aharonov-Bohm effect. The possibility of detecting lensed gravitation al waves is discussed in the context of upcoming gravitational wave detecto rs. [S0556-2821(99)03406-2].
