DMI-coupled qubits in a nonchiral waveguide yield tunable nonreciprocal transmission, directional steady-state entanglement, and photon superbunching—enabling isolators and routers without chiral waveguides.

Higher-order mean-field & perturbative methods model photon correlations in chirally coupled atom arrays, reproducing experimental superradiance data and showing MF4+ is required to capture second-order coherence from full inversion.

Exact analytical solutions derived for photon statistics in waveguide QED (N→∞, fixed optical depth). Shows exponentially enhanced superradiance before t≈1.59τ, followed by subradiance, with second-order coherence requiring finite-size effects to emerge.

Using MPS and frequency-space scattering theory, researchers show that photon localization in bimodal pulse envelopes dramatically alters two-photon nonlinear dynamics and transmitted correlation functions in single-atom waveguide-QED.

New optimal filter for giant cavity waveguide QED systems handles non-Markovian dynamics via delayed-state covariance matrices and interval-wise backward recursion, validated on coherent and Schrödinger cat states.
