They have done a good job, and their cooperation will be continued: After a successful review by an international commission of high-ranking scientists, the German-Japanese Center for Time, Constants and Fundamental Symmetries (TCFS) can start its second term. It will continue to strengthen the collaboration among German and Japanese institutes to advance most sensitive instruments for fundamental measurements in atomic and nuclear physics, antimatter and dark matter research, quantum optics and metrology. Three partners – the Max Planck Institutes for nuclear physics (MPIK) and for quantum optics (MPQ), the National Metrology Institute of Germany (PTB) and the Japanese flagship research institution RIKEN – will fund the centre in equal amounts with a total of around €7.5 million for an additional five years, starting in January 2024.
