kk, I haven't got around studying these things, since I'm away from university for two years now, and regarding field theory I'm more interested in statistical physics now. But I remember seeing your question being asked here:

I don't think I'm of much help here - I also don't know your background, I can at best try to motivate the Unruh effect - when I hear the two words, I think of the same principle, but only because I've never actually learned about black hole thermodynamics.

you're right, it's not apriori fixed or quantized. In the theory, discrete energy values pop up whenever you consider some bound system. Specifically, closed loops like when you go around in a circle are finite for fixed radius and so bound. This is e.g. why the solutions of the energy contributions from angular-like momenta (spin etc.) are given by some fixed numbers.
Because of interactions, you have light of all frequencies. Just consider black bodies.

what is the audience? if you speak of undergrad level, then i guess no single book will suffice. I don't really know any (englisch) book series I'd agree on totally. But I haven't read Laudau, it's probably nice.

light = water

light condensate, nice.
