Few-photon dispersion and correlations in two-dimensional chiral waveguide quantum electrodynamics*

The standard waveguide quantum electrodynamics (QED) paradigm studies the strong light-matter interaction and photon-photon correlations in lattices consisting of one-dimensional guided photonic modes coupled with many spatially distant quantum emitters. In this poster, we present our results related to few-photon dispersion properties when they propagate in two-dimensional lattices consisting of chiral waveguides strongly coupled with two-level quantum emitters. Our main focus in this work would be to examine how the higher dimensional waveguide QED models can impact the photonic band profile and the photon-photon correlations. This study will open new avenues to study strongly correlated higher dimensional many-body physics in the optical domain.
