The FOMO 2022 will be held at the International Center for Theoretical Physics in Trieste, a superb location for forefront science and an ideal atmosphere for relaxed discussions. It will be held from 12th September to 23rd September 2022. The topics will include matter-wave science & technologies with electrons, neutrons, atoms, ultracold ensembles, macromolecules, clusters & nanoparticles, tests of the foundations of physics at the interface to general relativity & to classical phenomena, inertial sensing: gravimetry, geodesy, navigation, quantum sensing, theory and modeling of quantum devices and matter-wave science in industry.
