Single delta potential. The time-independent Schrödinger equation for the wave function ψ(x) of a particle in one dimension in a potential V(x) is. where ħ is the reduced Planck constant, and E is the energy of the particle. The delta potential is the potential. where δ(x) is the Dirac delta function. It is called a delta potential well if ...

Delta bond. In chemistry, delta bonds ( δ bonds) are covalent chemical bonds, where four lobes of one involved atomic orbital overlap four lobes of the other involved atomic orbital. This overlap leads to the formation of a bonding molecular orbital with two nodal planes which contain the internuclear axis and go through both atoms.
Schematic depicting an intranet.
