The Green's functions used in the Korringa-Kohn-Rostoker method possess this property. A potential with this property can be simplified by assuming the potential is spherically symmetric within a certain radius and constant elsewhere; that assumption is used in the alternate plane wave method and is the muffin-tin approximation. A wavefunction which satisfies the Born-van Karman boundary conditions must possess this property. A potential with this property is constructed from a linear combination of atomic potentials in the tight binding model. Solving the Schrodinger equation in this type of potential gives rise to electronic band structure.

Awavefunction resulting from a potential with this property can be decomposed into the product ofa plane wave and a function with this property according to Bloch's theorem. For 10 points,name this property exhibited by crystal lattices, in which a structure repeats.
