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.

To solve the problem, first, identify the known and unknown quantities. The initial length (L) of the bridge is 1275 m, the coefficient of linear expansion (α) for steel is 12 x 10-6/°C, and the change in temperature (ΔT) is 55 °C.
Temperature and Thermal Equilibrium
The concept of temperature has evolved from the common concepts of hot and cold. The scientific definition of temperature explains more than just our sense of hot and cold. Temperature is operationally defined as the quantity measured with a thermometer. Furthermore, temperature is...
