Loudon’s treatment of photon correlations and coherence theory is unmatched. The book derives the famous Hanbury Brown-Twiss effect from first principles and introduces the in a way that is both mathematically precise and experimentally relevant. If you work with single-photon sources or quantum entanglement, you cannot avoid Loudon’s formalism. loudon quantum theory of light pdf better
