Laser-interferometer gravitational-wave optical-spring detectors

Abstract

Using a quantum mechanical approach, we show that in a gravitationalwave interferometer composed of arm cavities and a signal recycling cavity, e.g., the LIGO-II configuration, the radiation-pressure force acting on the mirrors not only disturbs the motion of the free masses randomly due to quantum fluctuations, but also and more fundamentally, makes them… (More)
