zitterbewegung

[¦tsid·ər·be′vā‚gu̇ŋ]
(quantum mechanics)
An oscillatory motion of an electron suggested in some interpretations of the Dirac electron theory, having a frequency greater than 4π mc 2/ h, where m is the electron's mass, c is the speed of light, and h is Planck's constant, or approximately 1.5 × 1021 hertz.

It came back unexpectedly about two millennia later under the guise of the Zitterbewegung or trembling motion of the relativistic electron that Erwin Schrodinger discovered in Dirac's theory of electrons and positrons.
In 1930, while analyzing possible solutions to the Dirac equation, Schrodinger identified a term called the Zitterbewegung that represents an unexpected oscillation whose amplitude is equal to the Compton wavelength.
(2) Zitterbewegung. Equations (149) can be solved, with the result for [x.sup.i](t) being [x.sup.i] = [a.sup.i] + d[p.sub.i]t + [c.sup.i] exp(-(2iH/[??])t).Thefirst and second terms are expected and describe a motion along the straight line.
As the Dirac theory has a vacuum including Zitterbewegung oscillations between positive and negative energy states and perfectly explains an interaction of a Dirac particle with an atomic structure of the materials, it gives a reasonable cosmological solutions for the early-time inflation and late-time acceleration of the universe [35].
2 exhibit oscillations which are produced by the systematic nature of the sampling and are connected with the oscillating term of Var(V) called Zitterbewegung (Matheron, 1971; Kieu, 1997; Garcia-Finana and Cruz-Orive, 2000).

Apart randomness, this interpretation agrees with the Schrodinger's zitterbewegung [4]; i.e., electrons describe random curvilinear paths (Compton's angular frequency) at the light speed.
The concept of q-deformation is also applied to the investigation of the connection of q-deformed DO with quantum optics and the existence of the well-known Zitterbewegung in relativistic quantum dynamics of the problem in question.
The first term on the right is routinely interpreted to represent the internal movements of the electron, the 'Zitterbewegung'.

The Dirac electron executes rapid oscillations superimposed on its normal average translational motion and this oscillatory motion is known as zitterbewegung and it was first shown by Schrodinger.
