Figure 3: Selective enhancement of the zero mode.
From: Selective enhancement of topologically induced interface states in a dielectric resonator chain
(a) Time evolution of the field intensity (normalized at each time step and colour coded by brightness; maximal intensity white, vanishing intensity black) in the SSH chain without absorption. The initial excitation is localized at the defect site at the centre of the system (indicated by the red arrow). All modes are participating in the propagation. (b) Time evolution of the field intensity in the complex SSH chain with absorption on B-sites. The zero mode is enhanced and dominates in the propagation.
