Magnon-phonon transport in spin insulatronics devices

许多粒子系统的分析可以通过使用“准粒子”来简化，这是一种数学工具，涉及选择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。我的工作重点是发展广义耦合磁振子声子准粒子输运方程，同时适用于结晶和非晶固体。这样的理论框架有可能使改进的自旋-绝缘体电子器件的设计成为可能，这为现有的电子器件提供了一种低耗散的替代方案。

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.
