强耦合磁振子-光子系统的自旋动力学相位和反共振

Spin dynamical phase and anti-resonance in a strongly coupled magnon-photon system

摘要:

通过微波透射测量,对强耦合磁振子-光子系统进行了实验研究。反共振,即微波传输的抑制,被观察到,指示磁振子响应和驱动微波场之间的相对相位变化。我们表明,这种反共振特性可以用来解释耦合磁振子-微波系统的相位演化,并应用这种技术来揭示磁振子暗模的相位演化。我们的工作为强耦合系统的相位分析提供了一个标准的程序,使每个子系统的相位特性,并可以普遍适用于其他强耦合系统。

英文摘要:

We experimentally studied a strongly coupled magnon-photon system via microwave transmission measurements. An anti-resonance, i.e. the suppression of the microwave transmission, is observed, indicating a relative phase change between the magnon response and the driving microwave field. We show that this anti-resonance feature can be used to interpret the phase evolution of the coupled magnon-microwave system and apply this technique to reveal the phase evolution of magnon dark modes. Our work provides a standard procedure for the phase analysis of strongly coupled systems, enabling the phase characterization of each subsystem, and can be generally applied to other strongly coupled systems.
