Landau Levels
... These eigenfunctions form Landau levels. First examine the lowest Landau level wavefunctions (n = 0 according to this scheme). y00 has some zero-point kinetic energy (the spread of the Gaussian); y01 represents a cyclotron orbit that closes on itself after one cycle; y02 represents a cyclotron orbit ...

Franck–Condon principle
The Franck–Condon principle is a rule in spectroscopy and quantum chemistry that explains the intensity of vibronic transitions. Vibronic transitions are the simultaneous changes in electronic and vibrational energy levels of a molecule due to the absorption or emission of a photon of the appropriate energy. The principle states that during an electronic transition, a change from one vibrational energy level to another will be more likely to happen if the two vibrational wave functions overlap more significantly.
