“…As a final consideration we observe that a state describing an electron not in complete equilibrium with its surrounding field was suggested by Feinberg [40] to represent the electron immediately after a scattering event of duration τ . In fact, due to causality requirements the electron can reach equilibrium only with its field within a region of size l ≤ cτ .…”

We consider a free charged particle interacting with an electromagnetic bath at zero temperature. The dipole approximation is used to treat the bath wavelengths larger than the width of the particle wave packet. The effect of these wavelengths is described then by a linear Hamiltonian whose form is analogous to phenomenological Hamiltonians previously adopted to describe the free particle-bath interaction. We study how the time dependence of decoherence evolution is related with initial particle-bath correlations. We show that decoherence is related to the time dependent dressing of the particle. Moreover because decoherence induced by the T = 0 bath is very rapid, we make some considerations on the conditions under which interference may be experimentally observed.

Reciprocal Schrödinger equation for scattering matrix ∂S(ω, r)/ i∂ω = τ (ω, r)S(ω, r) determines temporal function, its real part presents the Wigner-Smith duration of delay and imaginary part describes the duration of resulted (dressed) state formation. "Deduction" of this equation is executed by the Legendre transformation of classical action function with subsequent transition to quantum description and, in the covariant form, by a temporal variant of the Bogoliubov variational method. Temporal functions are expressed via propagators of fields, they are formally equivalent to adding a photon line of zero energymomentum to the Feynman graphs. As an apparent example they can be clearly interpreted in the oscillator model via polarization and conductivity of medium. It is shown that the adiabatic hypothesis in scattering theory represents an implicit account of temporal parameters. By these functions are described some renormalization procedures, their physical sense is refined, etc.
