Max Planck-RIKEN-PTB Center for

Time, Constants and Fundamental Symmetries

Research Topics

The broad research portfolio of the Max Planck-RIKEN-PTB Center for Time, Constants and Fundamental Symmetries encompasses crucial / timely / hot topics of current interests in metrology, specifically time, constants and fundamental symmetries. Particular areas of interest include new clock developments based on atoms, nuclei and highly charged ions, the improved determination of fundamental constants like the fine structure constant α, the Rydberg constant R, the proton charge radius, and stringent tests of fundamental interactions and their symmetries using, e.g. protons and antiprotons.
To be more specific, the scientific work includes the investigation of topics including the following:
