Identical particles Identical particles Identical particles, also called indistinguishable or indiscernible particles, are particles that cannot be distinguished from one another, even in principle. Species of identical particles include, but are not limited to elementary particles such as electrons, composite subatomic particles such as atomic nuclei, as well as atoms and molecules. Quasiparticles also behave in this way. Although all known indistinguishable particles are "tiny", there is no exhaustive list of all possible sorts of particles nor a clear-cut limit of applicability, as explored in quantum statistics. There are two main categories of identical particles: bosons, which can share quantum states, and
National Laboratory of Atomic, Molecular and Optical Physics National Laboratory of Atomic, Molecular and Optical Physics National Laboratory of Atomic, Molecular and Optical Physics (KL FAMO) is the national inter-university research center with the headquarters at Institute of Physics of Nicolaus Copernicus University in Toruń, Poland. Established in 2002, the Laboratory is focused on atomic, molecular, and optical physics (AMO). The activities of the ultra-cold matter group at KL FAMO are focused on Bose-Einstein condensation (the first BEC in Poland was created in 2007 in KL FAMO ), and on ultra-cold molecules' photoassociation spectroscopy. Two strontium optical lattice atomic clocks are operating at the KL FL FAMO. Together
