Distinguished Alumni Award Winner
A Search for Space-Time Correlations from the Planck Scale with the Fermilab Holometer
Time: 4:00 pm - 5:00 pm
Place: 2241 Chamberlin Hall (coffee at 3:30 pm)
Speaker: Steve Meyer, The University of Chicago
Abstract: Measurements are reported of high frequency cross-spectra of signals from the Fermilab Holometer, a pair of co-located 39 m, high power Michelson interferometers. The instrument obtains differential position sensitivity to cross-correlated signals far exceeding any previous measurement in a broad frequency band extending to the 3.8 MHz inverse light crossing time of the apparatus. A model of universal exotic spatial shear correlations that matches the Planck scale holographic information bound of space-time position states is excluded to 4.6 sigma significance.
Host: Peter Timbie
