  The response of a superconductor to a gravitational wave is shown to obey a
London-like constituent equation. The Cooper pairs are described by the
Ginzburg-Landau free energy density embedded in curved spacetime. The lattice
ions are modeled by quantum harmonic oscillators characterized by quasi-energy
eigenvalues. This formulation is shown to predict a dynamical Casimir effect
since the zero-point energy of the ionic lattice phonons is modulated by the
gravitational wave. It is also shown that the response to a gravitational wave
is far less for the Cooper pair density than for the ionic lattice. This
predicts a "charge separation effect" which can be used to detect the passage
of a gravitational wave.
