Expressions of a conserved 4-current and its density are examined in cases of electrically charged quantum particles. It is proven that the Noether theorem cannot be regarded as a sufficient condition that yields a consistent expression of a conserved 4-current, because electroma...

The sublevels of multi-quantum well structures (MQW) are calculated by the electron interference model and Kronig-Penney model, respectively. Comparing the values calculated theoretically with results measured in experiment, we can see that the values calculated theoretically by...
