    "abstract": "We analyze the transformation of quantum fields under conformal coordinate\ntransformations from inertial to accelerated frames, in the simple case of\nscalar massless fields in a two-dimensional spacetime, through the\ntransformation of particle number and its spectral density. Particle number is\nfound to be invariant under conformal coordinate transformations to uniformly\naccelerated frames, which extends the property already known for vacuum.\nTransformation of spectral density of particle number exhibits a redistribution\nof particles in the frequency spectrum. This redistribution is determined by\nderivatives of phase operators with respect to frequency, that is by time and\nposition operators defined in such a manner that the redistribution of\nparticles appears as a Doppler shift which depends on position in spacetime, in\nconformity with Einstein equivalence principle.",
