Significance Gravitational radiation provides a probe of unprecedented power with which to elucidate important astrophysical processes that are otherwise completely dark (e.g., black hole mergers) or impenetrable (e.g., supernova and early universe dynamics). Historically, the gap between propagating fluctuations in the spacetime metric and classical dynamical concepts such as energy and angular momentum conservation has bedeviled this subject. By now, there is a vast literature on this topic… Expand

Dynamical Casimir effect and the possibility of laser-like generation of gravitational radiation
In this paper, we address the question as to whether or not measurable sources for gravitational waves could possibly be made in the laboratory. Based on an analogy of the dynamical Casimir effectExpand
