(1/ω) Noise and the dynamical Casimir effect
Keyword(s):
The dynamical Casimir effect in quantum electrodynamics, which occurs for a frequency-modulated electromagnetic oscillator, is described in terms of reflection backward in time of the oscillator mode. From an experimental viewpoint, baekward-in-time reflections appear as radiated photons. The distribution of the electromagnetic radiation due to a modulation pulse is computed as a function of the frequency ω and is shown to exhbit a (1/ω) singularity in the limit ω → 0.
