We developed a photon scattering theory [1],[2],[3] to study multi-photon transports and bound state behaviors in low dimensional confined systems (e.g., the photonic waveguides and the photonic crystals) coupled to some quantum emitters. Using the path integral formalism, we show the exact results for the transmission spectra and second order correlation functions of scattered photons, which agree with the Markovian results from the quantum regression theorem. This formalism provides a systematical and convenient way to investigate the exotic photon statistics in the system with strong single-photon nonlinearities (e.g., Rydberg-EIT systems) and the generations of single photon (bundles) [4]. By considering the Markovian effects, we show that a single two-level impurity can bind multi-photons around it to form N-photon bound states [5] in the nonlinear photon bath.
