动态反作用磁力学
Dynamical Backaction Magnomechanics
摘要：
光学机械系统中由辐射压力产生的动态反作用已被证明是操纵机械振动的通用工具。值得注意的是，动力学反作用导致了机械谐振器冷却到基态，驱动声子激射，纠缠态的产生，以及光学弹簧效应的观察。在某些磁性材料中，机械振动可以通过磁致伸缩相互作用与磁激励（磁振子）相互作用，导致类似的磁振子诱导的动态反作用。在这篇文章中，我们直接观察磁振子诱导的动力学反作用对球形磁性样品的机械振动的影响。此外，动态反作用效应在最近的许多理论建议中发挥了至关重要的作用，因此，我们的工作为未来的实验工作提供了基础，追求许多这些理论建议。
英文摘要：
Dynamical backaction resulting from radiation pressure forces in optomechanical systems has proven to be a versatile tool for manipulating mechanical vibrations. Notably, dynamical backaction has resulted in the cooling of a mechanical resonator to its ground-state, driving phonon lasing, the generation of entangled states, and observation of the optical-spring effect. In certain magnetic materials, mechanical vibrations can interact with magnetic excitations (magnons) via the magnetostrictive interaction, resulting in an analogous magnon-induced dynamical backaction. In this article, we directly observe the impact of magnon-induced dynamical backaction on a spherical magnetic sample's mechanical vibrations. Moreover, dynamical backaction effects play a crucial role in many recent theoretical proposals; thus, our work provides the foundation for future experimental work pursuing many of these theoretical proposals.
