National Laboratory of Atomic, Molecular and Optical Physics with optical frequency combs they form the Polish Optical Atomic Clock (POZA). The POZA is a state-of-the-art optical atomic clock, collaboratively developed by scientists from the University of Warsaw, Jagiellonian University, and Nicolaus Copernicus University. The optical clocks' experimental group at KL FAMO is conducting research on, i.a., black-body radiation influence on the atomic transitions, shapes of molecules potentials by photoassociation spectroscopy, and on topological defects dark matter The studies of the quantum optics group are focused on experimental verifications of fundamental quantum mechanics predictions. In particular, the Laboratory is especially interested in quantum metrology, quantum information and quantum key
Molecules in stars Molecules in stars Stellar molecules are molecules that exist or form in stars. Such formations can take place when the temperature is low enough for molecules to form – typically around 6000 K or cooler. Otherwise the stellar matter is restricted to atoms (chemical elements) in the forms of gas or – at very high temperatures – plasma. Matter is made up by atoms (formed by protons and other subatomic particles). When the environment is right, atoms can join together and form molecules, which give rise to most materials studied in materials science. But certain environments, such as high temperatures,
