The analysis of systems of many particles can be simplified by working with 'quasiparticles', a mathematical tool which involves selecting a more natural basis in which to consider collective phenomena. Quasiparticles are especially useful for exploring conduction phenomena (such as heat, charge and spin) through solid materials. My work focuses on developing generalised equations for coupled magnon-phonon quasiparticle transport which are simultaneously applicable to both crystalline and amorphous solids. Such a theoretical framework has the potential to enable the design of improved spin-insulatronics devices, which offer a lower-dissipation alternative to existing electronics.

使用“准粒子”可以简化对许多粒子系统的分析，“准粒子”是一种数学工具，它涉及到选择一个更自然的基础来考虑集体现象。准粒子对于探索固体材料中的传导现象(如热、电荷和自旋)特别有用。我的工作集中在建立耦合磁振子-声子准粒子输运的普遍方程，该方程同时适用于晶态和非晶态固体。这样的理论框架有可能使改进的自旋绝缘电子器件的设计成为可能，它为现有电子产品提供了一种低功耗的替代方案。
