Fig. 6: Average number of photons 〈n〉 for anomalous edge states, and spatial-light structure.
From: Quantum origin of anomalous Floquet phases in cavity-QED materials

a 〈n〉 is plotted for two different pairs of anomalous edge states (see legend), 〈n〉 is plotted for both edge states. The vertical, dashed lines are the boundaries of the region [Ω−, Ω+]. b Weight of the anomalous edge states on each site of the chain i ∈ [1, 2N], for each photon subspace n (red for n = 0, blue for n = 1, and green for n = 2). All parameters are chosen as in Fig. 2: \(J=1,{J}^{{\prime} }=2,N=12\) unit cells, \(g=0.35,{n}_{\max }=50\).
