Magnon-phonon transport in spin insulatronics devices

对多粒子系统的分析可以通过使用“准粒子”来简化，“准粒子”是一种数学工具，它涉及选择一个更自然的基础来考虑集体现象。准粒子在探索通过固体材料的传导现象（如热、电荷和自旋）方面特别有用。我的工作重点是发展耦合磁子-声子准粒子输运的广义方程，同时适用于晶体和非晶态固体。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，它提供了现有电子器件的低耗散替代方案。

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.
