Fig. 3: Simulation results of time-dependent temperature distribution for topological edge modes.
From: Selectable diffusion direction with topologically protected edge modes
a Structure with the boundary between the topological and ordinary unit cells. The edge modes are excited in the region enclosed by the broken black line. Initial temperature is T0 = 293.15 K in the area except for the enclosed region. Regions Xleft (red line), Xright (blue line), Yabove (magenta line), and Ybelow (cyan line) are the nearest-neighboring sites from the heated and cooled regions. The thickness of the simulated model is 10 mm, the diameter of the site is d = 20 mm, and the distance between the nearest-neighboring sites is the same as the value for the model in Fig. 1 (L = 15 mm). b, c Snapshots of thermal diffusion at t = 0, 20, and 40 s for modes (b) A and (c) B in the area enclosed by the solid black square in (a).
