WebApr 15, 2024 · It has been shown that the bimodal probability has the influence on the localization lengths in binary disordered systems [60], [65].Now we consider how the phase diagram and localization properties are affected by the bimodal probability P in the SSH model. We first consider the topological properties in two limits of P = 0 and P = 1.The …

WebFeb 28, 2024 · This paper presents a detailed study investigating the effect of the material refractive index distribution at the local position of a glass–air disordered optical fiber (G-DOF) on its localized beam radius. It was found that the larger the proportion of the glass material, the smaller its localized beam radius, which means that the transverse Anderson … WebIn photonic crystal waveguides, fabrication induced disorder leads to propagation losses and Anderson-like localization , which could affect the threshold characteristics and the coupling efficiency between the modes of the two cavities and hence needs to …
WebApr 28, 2007 · An intermediate regime is found in which the ballistic and localized components coexist while diffusive dynamics is absent and evidence is found for a faster transition into localization under nonlinear conditions. We experimentally investigate the evolution of linear and nonlinear waves in a realization of the Anderson model using … WebThe transport of waves in pseudospin-1 systems exhibits many interesting phenomena, including super Klein tunneling, robust supercollimation, and unconventional Anderson localization. The transport properties of pseudospin-1 systems are distinct from their counterparts in pseudospin-1/2 systems, which will also be presented for comparison.
