Stark effect; The quantum harmonic oscillator Quantum mechanics is the extension of classical mechanics into the microscopic world, the world of atoms and molecules and of atomic nuclei and elementary particles. The need for a revision of the foundations of mechanics arises as a result of the wave-particle duality of matter, which manifests itself in systems of atomic dimensions. The Stark effect is the electric analogue of the Zeeman effect where a spectral line is split into several components due to the presence of a magnetic field. The Stark effect can be explained with fully quantum-mechanical approaches, but it has also been a fertile testing ground for semiclassical methods. Department of Physics, Peking University, Beijing 100871, China. The linear Stark effect for the first excited state of the hydrogen atom shows that, in the Apr 21, 2014 Abstract: The old quantum theory and Schrödinger's wave mechanics (and other forms of quantum mechanics) give the same results for the line 11.1.3 The Stark effect of perturbation theory is in Sakurai's book –J.J.

This puts a gap bigger than 50 years between the observations of the DC and AC versions of the Stark effect, a period in which a huge body of atomic and quantum physics was developed.

Optical Stark effect measured on GaAs quantum wells (Mysyrowicz et al. 1986) for three different pump intensities. Both the heavy and light hole exciton resonance are seen to shift to shorter wavelengths (courtesy of Dr. A. Mysyrowicz). The Stark effect is the phenomena of altering atomic energy levels by an external electric field. The external electric field can be applied to an atom or molecule and acts as a perturbation.

This application of perturbation theory was its first use in quantum mechanics. From: Stark effect in A Dictionary of Chemistry » Stark effect,, the splitting of spectral lines observed when the radiating atoms, ions, or molecules are subjected to a strong electric field. The electric analogue of the Zeeman effect (i.e., the magnetic splitting of spectral lines), it was discovered by a German physicist, Johannes Stark (1913). Returning to the Stark effect, let us examine the effect of an external electric field on the energy levels of the n = 2 states of a hydrogen atom. There are four such states: an l = 0 state, usually referred to as 2 S, and three l = 1 states (with m = − 1, 0, 1), usually referred to as 2P. This energy-shift is known as the Stark effect.

The Stark e ect is the electric analogue to the Zeeman e ect, i.e., a particle carrying an electric dipole moment, like the H-atom, will get a splitting of its energy levels when subjected to an exterior electric eld. The Hamiltonian of the H-atom thus has (another) additional term, the Stark term H Stark, which is perturbing the Coulomb Hamiltonian H
2014-04-21 · The old quantum theory and Schrödinger's wave mechanics (and other forms of quantum mechanics) give the same results for the line splittings in the first-order Stark effect in hydrogen, the leading terms in the splitting of the spectral lines emitted by a hydrogen atom in an external electric field. 2020-08-17 · On the Application of the Quantum Theory to the Problem of Relative Intensities of the Components of the Fine Structure and of the Stark Effect of the Lines of the Hydrogen Spectrum, p. 287 (1919);Über den Einfluß eines elektrischen Feldes auf die Feinstruktur der Wasserstofflinien (On the influence of an electric field on the fine structure of hydrogen lines), Zeitschrift für Physik, vol
The Stark effect has been explained on the basis of quantum mechanics.

In the absence of an external electric field, electrons and holes within the quantum well may only occupy states within a discrete set of energy subbands. In terms of quantum mechanics, the Stark effect is described by regarding the electric field as a perturbation on the quantum states and energy levels of an atom in the absence of an electric field. This application of perturbation theory was its first use in quantum mechanics. From: Stark effect in A Dictionary of Chemistry » Stark effect,, the splitting of spectral lines observed when the radiating atoms, ions, or molecules are subjected to a strong electric field.

The Stark effect for the n=2 states of hydrogen requires the use of degenerate state perturbation theory since there are four states with (nearly) the same energies.
