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
Thermal radiation with each other. These atoms and molecules are composed of charged particles, i.e., protons and electrons, and kinetic interactions among matter particles result in charge-acceleration and dipole-oscillation. This results in the electrodynamic generation of coupled electric and magnetic fields, resulting in the emission of photons, radiating energy away from the body through its surface boundary. Electromagnetic radiation, including light, does not require the presence of matter to propagate and travels in the vacuum of space infinitely far if unobstructed. The characteristics of thermal radiation depend on various properties of the surface it is emanating from, including its temperature, its spectral
