Zitterbewegung and gravitational Berry phase
arXiv:1202.5716 · doi:10.1016/j.physleta.2012.02.057
Abstract
Berry phases mix states of positive and negative energy in the propagation of fermions and bosons in external gravitational and electromagnetic fields and generate Zitterbewegung oscillations. The results are valid in any reference frame and to any order of approximation in the metric deviation.
