Robust topological temperature localization in thermal rock-paper-scissors chainOA
Emerging topological thermal physics has revolutionized thermal management with topological thermal metamaterials,but most of them only consider passive/static thermal diffusion.Inspired by ecological dynamics,we investigate the topological thermal physics in an active/dynamic three-body heat-transfer system connected with Peltier modules,in which the cyclic interaction is exemplified by the rock-paper-scissors(RPS)chain.Numerical simulations demonstrate a robust temperature localization phenomenon against parametric disturbance and structural perturbations,and topological phase transition in a thermal RPS chain is discussed via a topological band-theory analysis of the corresponding Hamiltonian.Our findings establish a framework for exploring dynamic topological phenomena in non-equilibrium thermal transport,offering new pathways for active thermal management.
