More photon questions

  1. Sep 26, 2015 #1
    I’ve seen references on here to photons being “excitations of the EM field”. I have a few questions about those “excitations”.
    • I assume they are eigen-solutions of the 1D wave equation?

    • What are the boundary conditions on the solutions?

    • Is a single photon a single eigen-mode, or a supper-position of more than one mode?

    • Are the solutions normal or complex modes?
    The reason for some of the questions is that I don’t see how a SINGLE NORMAL mode can transmit information, energy, momentum, or whatever from one place to another.

    Recommended references appreciated.
