Novel Clocks for New Physics Searches

October 4, 2021 - 11:00am
Marianna Safronova
University of Delaware

The development of atomic clocks with systematic uncertainties in the 10-18 range enables searches for the variation of fundamental constants, dark matter, and violations of Lorentz invariance. I will give an overview of dark matter searches and other fundamental physics studies with atomic and nuclear clocks and focus on development of clocks with the highest sensitivities to new physics. I will discuss recent advances in theory of novel clocks based on highly-charged ions and efforts to develop a nuclear clock. Related recent methodology developments and resulting capabilities of the state-of-the-art atomic methods to compute atomic properties of complicated atomic species will be presented. I will also report a release of the first version of a new online portal for high-precision atomic data and computation. Future plans to add data for more systems as well as to release computer codes are discussed.

Joint Quantum Institute Seminars take place live each Monday during Fall and Spring Semesters, 11:00 a.m. - 12:00 p.m. Eastern Time, in Room 2400 of the Atlantic Building. University of Maryland affiliates may participate using Zoom. The Seminars are also simulcast world-wide on the Joint Quantum Institute YouTube channel, , which supports audience participation in the chat interface.
