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
Cluster (physics) Cluster (physics) In physics, the term clusters denotes small, multiatom particles. As a rule of thumb, any particle of somewhere between 3 and 3×10 atoms is considered a cluster. Two-atom particles are sometimes considered clusters as well. A two atom particle may also be a molecule. The term can also refer to the organization of protons and neutrons within an atomic nucleus, e.g. the alpha particle (also known as "α-cluster"), consisting of two protons and two neutrons (as in a helium nucleus). Although first reports of cluster species date back already to the 1940s, cluster science emerged as a separate
