... the wave function of an electron is a probability amplitude, and its modulus square gives the probability density of finding the electron in a certain location at a given instant. This is usually called the probability interpretation of the wave function. Notwithstanding its great success, the proba ...

Solve for the values of the wave field (wave function). 2. Use the wave function to calculate the probability of finding our part ...

... well in 3D: The potential is zero inside a region of radius a and is VH for r > a. Then we can rewrite the timeindependent Schrödinger equation in 3D for this potential in spherical coordinates and use separation of variables ({r, ϑ, ϕ}). Because of symmetry, the wavefunction is a constant in ϑ and ...

Propagator

In quantum mechanics and quantum field theory, the propagator gives the probability amplitude for a particle to travel from one place to another in a given time, or to travel with a certain energy and momentum. In Feynman diagrams, which calculate the rate of collisions in quantum field theory, virtual particles contribute their propagator to the rate of the scattering event described by the diagram. They also can be viewed as the inverse of the wave operator appropriate to the particle, and are therefore often called Green's functions.
