Abstract
This paper demonstrates the selection of thermal diffusion direction using topologically protected edge modes in a honeycomb-shaped structure. By adjusting the ratio of effective diffusivities, a topological phase transition is controlled, creating edge modes that induce thermal polarization. Numerical and analytical studies show that the temperature corresponding to these edge modes provides directional heat balance, making the system robust to defects.
