Abstract

The electron vacuum fluctuations measured by (ψψ) do not vanish in an externally applied electric field ε. For an exactly constant field, that is for vacuum fluctuations in presence of a constant accelerating force, we show that (ψψ) has a Boson-like structure with spectral state density tanh^-1(E/m) and temperature T_M = eε/mπ = a _v/π. Considering the vacuum fluctuations of 'classical' gyromagnetic ratio g = 1 particles we find Fermi-like structure with the same spectral state density at a smaller temperature T₁ = a _v/2π which corresponds to the Unruh temperature of an accelerated observer.
