In the context of quantum mechanics and condensed matter physics, "gas in a harmonic trap" typically refers to a system of ultracold atoms or particles that are confined by a harmonic potential. This scenario is commonly encountered when studying Bose-Einstein condensates (BECs), fermionic systems, or other quantum gases subjected to external trapping forces.
