zitterbewegung

(redirected from Zitterbewegung motion)

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.

In the zitterbewegung motion, the electron appears vibrating rapidly with a very high frequency equal to 2m[c.sup.2][[??].sup.-1] and with internal velocity equal to the velocity of light.
Another important aspect of the photon is its internal zitterbewegung motion. It is well known from the first observation of Schrodinger [17] that a Dirac electron possesses zitterbewegung motion which is the oscillatory motion of the electron with very high frequency [omega] = 2m[c.sup.2]/h with internal velocity equal to the velocity of light.
