Gravity-wave interferometers as probes of a low-energy effective quantum gravity - art. no. 024015

The interferometry-based experimental tests of quantum properties of space- time which the author sketched out in a recent short paper are here discuss ed in a self-contained fashion. In addition to providing detailed derivatio ns of the results already announced in the previous paper, some new results an also derived; in particular, the analysis is extended to a larger class of scenarios for space-time fuzziness. It is argued that these studies cou ld be helpful for the search for a theory describing a first stage of parti al unification of gravity and quantum mechanics.
