==== Jour Fixe ==== Members in attendance: NJ, SS, kHz Atom Lab: * Ongoing measurements for higher order lattice AC Stark shifts. * Already see some indications of higher order shifts. Need more measurements to be fully sure and to get the shift parameters within uncertainties. Resonator Lab: * Time lost due to poster preparation for DPG which did not happen eventually * Steffen working on calculations for thermal noise in resonators (contributions besides the typical Brownian noise). Next meeting: 16.03.2020
