Hi! I'm new here, but I hope that someone would evenly help me!(adsbygoogle = window.adsbygoogle || []).push({});

My first question is about the problem (3.3 on page 100 from Loudon - The Quantum Theory of Light 3ed) in the attachment; the second question is about discussing (I)the physical origin of fluctuations of the electromagnetic radiation, in the classical and in the quantum model, and (II) which kind of correlation among the em radiation features brings to the limit of the coherent state (minimun uncertainty state with (deltaX)^2=(deltaY)^2) and which one else gives the squeezed states (mus with (deltaX)^2 not equal to (deltaY)^2).

Thank you very much to all of you that every night and day discuss within the forum.

Thanks for reading!

Fran
