- Abstract: We study the effects of the electromagnetic vacuum on the motion of a
nonrelativistic electron. First, we derive the equation of motion for the
expectation value of the electron's position operator. We show how this
equation has the same form as the classical Abraham-Lorentz equation but, at
the same time, is free of the well known runaway solution. Second, we study
decoherence induced by vacuum fluctuations. We show that decoherence due to
vacuum fluctuations that appears at the level of the reduced density matrix of
the electron, obtained after tracing over the radiation field, does not
correspond to actual irreversible loss of coherence.
