Explore the fascinating world of optical clocks in this 50-minute lecture by Christian Lisdat, presented at the Workshop on "Blackbody Radiation Induced Effects and Phenomena" at the Erwin Schrödinger International Institute for Mathematics and Physics. Delve into the operation principles of optical clocks and understand the intrinsic differences between systems using laser interrogation of single ions versus neutral atoms. Examine the current performance of optical clocks through selected examples, with a focus on accuracy in reproducing unperturbed atomic transition frequencies. Learn about the significant impact of environmental thermal radiation on frequency shifts and discover various approaches to determine, correct, and minimize these offsets. Gain insights into experimental strategies employed to control and mitigate frequency shifts, enhancing your understanding of cutting-edge timekeeping technology.
