Diffusive skin effect and topological heat funneling

[摘要] Non-Hermitian systems can house a range of unusual physical phenomena such as the skin-effect which has been typically observed in optical lattices and electrical circuits. Here, the authors show the non-Hermitian skin effect in thermal transport, demonstrating that the topologically protected heat flow can be realized by using thermal metamaterials.
