Loudon Quantum Theory Of Light Pdf -

Rodney Loudon’s "The Quantum Theory of Light" is a definitive graduate-level textbook that bridges classical electromagnetism with quantized field theory, covering topics from photon statistics to the Jaynes-Cummings model [1]. The updated third edition includes expanded content on quantum information, entanglement, and squeezed states, establishing the "Loudon" standard for understanding light-matter interactions and experimental quantum optics [1].

• Coherent state |α>: photon number distribution P(n)=e^(-|α|^2)|α|^(2n)/n!, so ⟨n⟩=|α|^2 and Var(n)=|α|^2 → g^(2)(0)=⟨a†a†aa⟩/⟨a†a⟩^2 = 1.
• Single-photon state |1>: ⟨a†a⟩=1 and ⟨a†a†aa⟩=0 → g^(2)(0)=0 (perfect antibunching).

• Classical electromagnetism as a precursor to quantization
• Quantization of the radiation field (photons)
• Coherence properties: first-order (interference) and second-order (Hanbury Brown–Twiss effect)
• Photon statistics (Poissonian, sub-Poissonian, thermal light)
• Atom–photon interactions: spontaneous emission, the optical Bloch equations
• Nonlinear quantum optics: parametric down-conversion, four-wave mixing
• Squeezed states of light and quantum non-demolition measurements
