kvanttijaksoisuuden
Kvanttijaksoisuuden, known in English as quantum periodicity, is a phenomenon observed in certain quantum mechanical systems where a property exhibits periodic behavior as a function of some parameter. This parameter is often related to an applied magnetic field, a change in potential, or another external influence. The periodicity arises from the wave-like nature of quantum particles and the discrete energy levels that quantum systems can possess.
A prominent example of quantum periodicity is the Shubnikov–de Haas effect, observed in conductors at low temperatures
Another related phenomenon is the de Haas–van Alphen effect, which manifests as oscillations in the magnetic
