Cavity QED II: Quantum Fluctuations
In Chap. 15 we made some progress applying linear fluctuation theory to the system of many atoms in a cavity. Conditions of strong dipole coupling were included, assuming the coupling was strong only in the many-atom sense. Ultimately, cavity QED is concerned with strong coupling for single atoms, though-i.e., with g >> κ, γ/2 (alternatively 2C1 >> 1), conditions that invalidate the small-noise assumption upon which the linear theory of fluctuations rests (Sect. 13.1).
