Weak Interaction Discussion Group Talk (WIDG): Lee McCuller, MIT, “First results from the Fermilab Holometer testing space-time correlations from Planckian diffraction”

The Holometer is designed to test for a Planck-diffraction scale uncertainty in resolving position over large baselines. The experiment overlaps two independent 40 meter optical Michelson inteferometers to detect the proposed uncertainty as a common broadband length fluctuation. I will present results from cross correlating two 2kW interferometers over 150 hours, including systematics studies to limit spurious sources of background correlation. The observing interval provides statistical power to test the underlying theory, where noncommutative geometry is normalized to relate position states against Black hole entropy bounds of the Holographic principle.
