Title: Few-photon optical diode in a chiral waveguide
Authors: Jin-Lei Tan, Xun-Wei Xu, Jing Lu, Lan Zhou
Abstract summary: We study the coherent transport of one or two photons in a 1D waveguide chirally coupled to a nonlinear resonator. Although the resonator acts as a non-reciprocal phase shifter, light transmission is reciprocal at one-photon level.

Abstract: We study the coherent transport of one or two photons in a 1D waveguide chirally coupled to a nonlinear resonator. Analytic solutions of the one-photon and two-photon scattering is derived. Although the resonator acts as a non-reciprocal phase shifter, light transmission is reciprocal at one-photon level. However, the forward and reverse transmitted probabilities for two photons incident from either the left side or the right side of the nonlinear resonator are nonreciprocal due to the energy redistribution of the two-photon bound state. Hence, the nonlinear resonator acts as an optical diode at two-photon level.

Quantum noise induced nonreciprocity for single photon transport in parity-time symmetric systems [1.6597433198079004]
We show nonreciprocal light propagation for single-photon inputs due to quantum noise in coupled optical systems with gain and loss. We consider two parity-time ($mathcalPT$) symmetric linear optical systems consisting of either two directly coupled resonators or two finite-length waveguides evanescently coupled in parallel.

Vortices are hallmark of nontrivial dynamics in nonlinear physics. We report on the realization of quantum vortices resulting from a strong photon-photon interaction in a quantum nonlinear optical medium. For three photons, the formation of vortex lines and a central vortex ring attests to a genuine three-photon interaction.

Undamped Rabi oscillations due to polaron-emitter hybrid states in non-linear photonic wave guide coupled to emitters [0.0]
We study the collective dynamics of two non-interacting two-level emitters coupled to a structured wave guide. We identify parameter regimes where the system displays fractional populations and essentially undamped Rabi oscillations. Our work demonstrates that emitter-photon coupling can lead to an all-to-all momentum space interaction between two-photon bound states and tunable non-Markovian dynamics.
