爱因斯坦-德哈斯纳米转子
Einstein-de Haas Nanorotor
摘要：
我们提出了一个纳米级转子嵌入两个铁磁电极之间，由自旋注入驱动。自旋-旋转耦合允许该纳米转子在反平行磁化配置中的铁磁电极之间的恒定电流流动下从注入的自旋连续接收角动量。我们开发了这种角动量转移的量子理论，并表明从进动状态到睡眠顶态的松弛过程是至关重要的，通过求解主方程的纳米转子的有效驱动。我们的工作阐明了一个有效的驱动纳米转子的一般策略。
英文摘要：
We propose a nanoscale rotor embedded between two ferromagnetic electrodes that is driven by spin injection. The spin-rotation coupling allows this nanorotor to continuously receive angular momentum from an injected spin under steady current flow between ferromagnetic electrodes in an antiparallel magnetization configuration. We develop a quantum theory of this angular momentum transfer and show that a relaxation process from a precession state into a sleeping top state is crucial for the efficient driving of the nanorotor by solving the master equation. Our work clarifies a general strategy for efficient driving of a nanorotor.
