Stark effect hamiltonian

The Stark effect is the shifting and splitting of spectral lines of atoms and molecules due to the presence of an external electric field. It is the electric-field analogue of the Zeeman effect, where a spectral line is split into several components due to the presence of the magnetic field. Although initially coined for the … Visa mer The effect is named after the German physicist Johannes Stark, who discovered it in 1913. It was independently discovered in the same year by the Italian physicist Antonino Lo Surdo, and in Italy it is thus sometimes called … Visa mer Overview An electric field pointing from left to right, for example, tends to pull nuclei to the right and electrons to … Visa mer • Zeeman effect • Autler–Townes effect • Quantum-confined Stark effect • Stark spectroscopy • Inglis–Teller equation Visa mer The Stark effect is at the basis of the spectral shift measured for voltage-sensitive dyes used for imaging of the firing activity of neurons.

Webb258 12 The Stark Effect The principal reason for the difference between hydrogen and other atoms occurs because the Stark effect Hamiltonian has odd parity. As a consequence, the first-order perturbation term cancels. The only exception from this is when two states of different parities happen to be degenerate, and this is the case for … WebbLet us study this effect, in the linear approximation, for a hydrogen-like atom/ion. Taking the direction of the external electric field E (which is practically always uniform on the atomic scale) for the z -axis, the perturbation may be represented by the following Hamiltonian: ˆH ( 1) = − Fˆz = − qEˆz = − qErcosθ.
