We consider a two-dimensional extension of the one-dimensional waveguide quantum electrodynamics and investigate the nature of linear excitations in two-dimensional arrays of qubits coupled to networks of chiral waveguides. We show that the combined effects of chirality and long-range photon-mediated qubit-qubit interactions lead to the emergence of the two-dimensional flat bands in the polaritonic spectrum, corresponding to slow strongly correlated light.

二维手性波导量子电动力学:长距离量子位相关和平坦带暗极化子

我们考虑一维波导量子电动力学的二维扩展,并研究耦合到手性波导网络的量子比特的二维阵列中线性激发的性质。我们表明,手性和远距离光子介导的量子位-量子位相互作用的组合效应导致在极化谱中出现二维平坦带,对应于缓慢的强相关光。
