Exploring Dynamically Adjustable Topological Edge States in Thermal Diffusion-Advection Systems
Topological edge states, once thought to be exclusive to quantum and electronic systems, are now revealing their potential in classical environments—particularly in thermal systems. Our recent study investigates how dynamically tunable topological edge states can be engineered within diffusion-advection frameworks, opening new pathways for controlling thermal energy transport.
In typical thermal systems, heat transfer is governed by a combination of diffusion and advection. However, by designing specific boundary conditions and internal flow patterns, it becomes possible to emulate topological invariants that result in robust, localized thermal currents along system edges. These edge modes are not only resilient to perturbations and defects, but in our model, they can also be dynamically controlled by tuning advection velocities or geometric parameters in real-time.
This innovation offers significant potential for thermal metamaterials, adaptive heat guides, and non-equilibrium energy systems where directionality and protection from backscattering are crucial. The method blends topological physics, nonlinear dynamics, and fluid-thermal interactions, pushing the boundaries of how we understand and manipulate classical transport phenomena.
Our results are validated through both numerical simulations and analytical topological phase analysis, confirming the emergence of unidirectional, non-reciprocal heat channels that persist under structural disorder. This makes them ideal for energy-efficient designs, thermal logic circuits, and programmable heat-flow technologies.
As the demand for reconfigurable thermal devices grows in fields like aerospace, microelectronics, and energy harvesting, our findings pave the way for integrating topological principles into real-world applications far beyond quantum systems.
