Background

Efficient thermal management is a critical challenge in modern electronic devices, particularly in high-performance computing and quantum technologies. The ability to precisely control heat generation and dissipation directly impacts device performance, reliability, and lifespan. Recently, the concept of metamaterials, originally developed to manipulate electromagnetic waves, has been applied to control heat flow, giving rise to “thermal metamaterials.” Two-dimensional (2D) materials and nanostructures, controllable at the atomic level, hold the potential to exhibit nonlinear thermal transport phenomena and quantum coherence effects. These are key to unlocking new thermal management strategies beyond the scope of conventional heat conduction theories. However, a theoretical framework for understanding and engineering these complex phenomena remains underdeveloped.

Key Findings / Results

This preprint paper explores the advanced topic of nonlinear coherent transport in 2D thermal metamaterials, integrally discussing its connections to solitons, topological defects, and quantum computing. The main findings of the research are as follows:

• Discovery of Nonlinear Coherent Modes: The study theoretically demonstrates the existence of wave-like nonlinear coherent modes in heat conduction that cannot be explained by conventional diffusive transport models. These modes arise from specific geometric designs and the nonlinear response of materials, potentially enabling highly efficient and directed heat transfer.
• Geometrically Driven Heat Channeling and Topological Defects: It is shown that the microscopic geometric structure of materials plays a crucial role in channeling heat flow (concentrating heat into specific pathways). Furthermore, topological defects within the lattice (e.g., local irregularities in atomic arrangements) are identified as potential factors that can alter heat transport pathways and influence the propagation of thermal waves.
• Relevance to Quantum Computing: The research proposes that quantum computing tools can be utilized as concrete means to solve complex problems in nonlinear thermal transport theory. By employing quantum algorithms, it becomes possible to more efficiently explore and understand multivariate interactions—such as microscopic nonlinearity, geometric effects, and temperature dependence—that are challenging for classical simulations.
• Validation of Theoretical Predictions: Experimental and computational results, including ultra-low thermal conductivity, high carrier mobility, and strong anisotropy in PdSSe monolayers and silicon phononic crystal nanostructures, are cited as supporting evidence for the theoretical predictions proposed in this study. These materials are promising platforms for exhibiting nonlinear thermal transport and quantum effects.

The work establishes a novel theoretical framework that integrates nonlinear coherent modes, hydrodynamic universality, and geometrically driven channeling for 2D thermal metamaterials, offering a fresh perspective on heat control.
