Complementary probes of gravitational radiation states
Sreenath K. Manikandan, Frank A. Wilczek
Abstract
We demonstrate that statistical fluctuations in resonant radiation detectors operating in homodyne and heterodyne modes offer additional, complementary information to that obtained from their direct operation as click detectors. We use this to refine tests of the coherent-state hypothesis, which is of special interest for gravitational wave fields.
