We explore the use of ultracold atoms and molecules for quantum science and technology.

Our goals include the use of dipolar molecules, to realize new forms of quantum matter and gain insights into the foundations of molecular collisions and chemistry. Moreover, we study molecules that facilitate tabletop precision searches for new physics beyond the Standard Model of particle physics. Finally, we also develop compact experimental setups to manipulate single atoms and molecules for technological applications.

Laser cooling of fermionic 137BaF molecules for precision measurements of parity violation

Laser cooling of fermionic 137BaF molecules for precision measurements of parity

Two levels are great for qubits, but molecules can take it to the next level — currently 112 of them, to be exact.

We've controlled this complexity to realize laser cooling of previously intractable fermionic 137BaF molecules, to our knowledge the most complex molecule laser-cooled to date. 

This sets the stage for sensitive tests of parity violation and the Standard Model of particle physics using these molecules!

Great work by lead author Felix Kogel, who also theoretically proposed the cooling scheme for such molecules four years earlier (https://iopscience.iop.org/article/10.1088/1367-2630/ac1df2, opens an external URL in a new window), as well as by Tatsam Garg and Marian Rockenhäuser
