The passage around this formula

An inertial worldline’s Wightman function is the flat-space, two-point function of the free vacuum, whose Fourier transform against e−iΩΔτe^{-i\Omega\Delta\tau} has support only for Ω\Omega<0 — this is nothing more exotic than vacuum stability, the same textbook fact that says an unaccelerated atom in its ground state, coupled to the electromagnetic vacuum, never spontaneously jumps up in energy [ 6 ] . Consequently \dot{\mathcal…
