  We have recently suggested a new approach and design of an ultra-sensitive
gravity wave detector antenna based on superconductivity. The idea was
described in a short paper [1]:
http://iopscience.iop.org/1742-6596/507/4/042013, in entries on the arXiv [2]:
arXiv:1111.2655, and at various conferences. Here we would like to explain in a
more detailed manner the motivation for and the advantages of our approach.
