Quantum theory of light scattering in a one-dimensional channel: Interaction effect on photon statistics and entanglement entropy

Understand

We provide a complete and exact quantum description of coherent light scattering in a one-dimensional multi-mode transmission line coupled to a two-level emitter.

• Using recently developed scattering approach we discuss transmission properties, power spectrum, the full counting statistics and the entanglement entropy of transmitted and reflected states of light.
• Our approach takes into account spatial parameters of an incident coherent pulse as well as waiting and counting times of a detector.
• We describe time evolution of the power spectrum as well as observe deviations from the Poissonian statistics for reflected and transmitted fields.
