Schrödinger's equation

where ℏ denotes the reduced Planck's constant, m is the mass of the particle, V denotes potential energy, and ∇2 denotes the Laplacian. The wave function ψ is a superposition of states ψn(x,t) which satisfy the time-independent Schrödinger equation

where En denotes energy of the nth state. More concisely, this may be written Hψn = Enψn, so that ψn is an eigenstate of the Hamiltonian H. See Copenhagen interpretation, measurement, observable.
