• Abstract: Using Dirac equation together with the Wigner distribution function,the trembling motion,known as Zitterbewegung effect,of moving electrons in quasi-one-dimensional relativistic quantum plasma is theoretically investigated.The relativistic Wigner matrix is used to calculate the mean values of the position and velocity operators for a Dirac gas of electrons.It is found that the oscillatory behavior of measurable quantities could be associated with the Zitterbewegung effect which manifests itself as a damping interference pattern stemming from mixing the positive and negative dispersion modes of Dirac particles.

Remarkably, the action models the effects of general relativity on the motion of nonrelativistic particles, with the values of the emergent curvature and speed of light determined by the field spatial distribution and frequency.

  Zitterbewegung of Dirac particles is underlain by a more fundamental and universal interference behavior without classical analogs. We reveal such an interference pattern in phase space, which underlies but goes beyond Zitterbewegung. Besides being of fundamental importance, the demonstrated nonclassical effects are useful in quantum technology.
