Allgemein

Theoretical physics aims at describing observable phenomena and predicting possible effects using a huge mathematical toolbox. A powerful approach is considering the system as a so-called Hermitian system. This theoretical approach results in observable numbers like the position, the momentum or energy values that can be measured in real-world experiments.

Clapping your hands generates sound. At concerts and in big stadiums, even huge crowds easily synchronize their applause to a repetitive timed beat. Their clapping is coherent. Single excited atoms can also show coherence.

The winter 2021/22 program of the QuCoLiMaTalks is now online. The QuCoLiMaTalks take place, unless otherwise noted, Tuesdays during the semester at 12:00 - still online for now. More information of the upcoming talks can be found at www.qucolima.de/talks. (Note that starting this semester, t...

The first annual meeting and summer school of the TRR 306 QuCoLiMa took place from 11. October - 15. October in Erlangen. All project leaders and doctoral researchers gathered in a hybrid format. After the approval by the DFG, this was the first in-person meeting of the TRR 306. More details a...

If you read the term ‚color center’, you may not necessarily think of quantum physics. Color centers are tiny defects in an otherwise perfectly built crystal. What at first sounds like a disadvantage is in fact a highly promising pathway for modern quantum technologies.
