Zitterbewegung in Radiative Processes
نویسنده
چکیده
The zitterbewegung is a local circulatory motion of the electron presumed to be the basis of the electron spin and magnetic moment. A reformulation of the Dirac theory shows that this interpretation can be sustained rigorously, with the complex phase factor in the wave function describing the local frequency and phase of the circulatory motion directly. This reveals the zitterbewegung as a mechanism for storing energy in a single electron, with many implications for radiative processes.

Some Remarks about Mass and Zitterbewegung Substructure of Electron
Some remarks about mass and Zitterbewegung substructure of electron. Abstract-It is shown that the electron Zitterbewegung, that is, the high-frequency microscopic oscillatory motion of electron about its centre of mass, originates a spatial distribution of charge. This allows the point-like electron behave like a particle of definite size whose self-energy, that is, energy of its electromagnet...
متن کاملThe Zitterbewegung Interpretation of Quantum Mechanics
The zitterbewegung is a local circulatory motion of the electron presumed to be the basis of the electron spin and magnetic moment. A reformulation of the Dirac theory shows that the zitterbewegung need not be attributed to interference between positive and negative energy states as originally proposed by Schroedinger. Rather, it provides a physical interpretation for the complex phase factor i...

Abstract. This paper investigates the properties of spin-1/2 particle Zitterbewegung in the presence of a general curved space-time background described in terms of Fermi normal co-ordinates, where the spatial part is expressed using general curvilinear co-ordinates. Adopting the approach first introduced by Barut and Bracken for Zitterbewegung in the local rest frame of the particle, it is sho...
متن کاملZitterbewegung of electronic wave packets in III-V zinc-blende semiconductor quantum wells.
We study the zitterbewegung of electronic wave packets in III-V zinc-blende semiconductor quantum wells due to spin-orbit coupling. Our results suggest a direct experimental proof of this fundamental effect, confirming a long-standing theoretical prediction. For electron motion in a harmonic quantum wire, we numerically and analytically find a resonance condition maximizing the zitterbewegung.
متن کاملZitterbewegung in Quantum Mechanics
The possibility that zitterbewegung opens a window to particle substructure in quantum mechanics is explored by constructing a particle model with structural features inherent in the Dirac equation. This paper develops a self-contained dynamical model of the electron as a lightlike particle with helical zitterbewegung and electromagnetic interactions. The model admits periodic solutions with qu...
