Causal signal transmission by quantum fields. I: Response of the harmonic oscillator
2008 (English)In: Annals of Physics, ISSN 0003-4916, E-ISSN 1096-035X, Vol. 323, no 8, 1963-1988 p.Article in journal (Refereed) Published
It is shown that response properties of a quantum harmonic oscillator are in essence those of a classical oscillator, and that, paradoxical as it may be, these classical properties underlie all quantum dynamical properties of the system. The results are extended to noninteracting bosonic fields, both neutral and charged.
