SPECIAL ISSUE — Selected Essays from the Annual Essay Competition of the Gravity Research Foundation 2020 and Invited Papers Dedicated to John D. Barrow (1952–2020)
Editor: D. V. Ahluwalia

Abstract

We will use Fisher information to properly analyze the quantum weak equivalence principle. We argue that gravitational waves will be partially reflected by superconductors. This will occur as the violation of the weak equivalence principle in Cooper pairs is larger than the surrounding ionic lattice. Such reflections of virtual gravitational waves by superconductors can produce a gravitational Casimir effect, which may be detected using currently available technology.

This essay received an Honorable Mention in the 2020 Essay Competition of the Gravity Research Foundation.
