Bloch theorem. A theorem that specifies the form of the wave functions that characterize electron energy levels in a periodic crystal. Electrons that move in a constant potential, that is, a potential independent of the position r, have wave functions that are plane waves, having the form exp(i k Â· r).he theorem that the lowest state of a quantum-mechanical system without a magnetic field can carry no current. (solid-state physics). The theorem that, in a periodic structure, every electronic wave function can be represented by a Bloch function.
The fundamental theorem of calculus is a theorem that links the concept of the derivative of a function with the concept of the function's integral.he fundamental theorem of calculus relates differentiation and integration, showing that these two operations are essentially inverses of one another. Before the discovery of this theorem, it was not recognized that these two operations were related.
