标题： Explosive growth of bistability in a cavity magnonic system

摘要： 我们对包含磁非线性的腔磁子系统中双稳态的爆炸性增长进行了理论研究。 在这个系统中，磁子和光子之间的耦合产生了腔磁子极化子。 当驱动光子样极化子模式时，随着驱动功率的增加，双稳态可以发生突然的转变，导致双稳态区域的爆炸性增长，增长数倍。 相反，驱动磁子样极化子模式只会产生正常的双稳态。 这取决于产生双稳态所需的最小驱动功率是否随驱动频率呈非单调变化。 此外，尽管仅驱动光子样极化子模式，由于光-物质相互作用，在微波传输中，光子样和磁子样极化子模式可以同时表现出双稳态的爆炸性增长。 我们的研究揭示了非线性腔磁子系统的隐藏方面，并为基于这一新特性的腔自旋电子器件提供了潜在的应用。 显示英文摘要

摘要： We conduct a theoretical investigation into explosive growth of bistability in a cavity magnonic system incorporating magnetic nonlinearity. In this system, the coupling between the magnon and photon generates the cavity magnon polaritons. When driving the photon-like polariton mode, the bistability can undergo a sudden transition with the increase of the driving power, resulting in an explosive growth of the bistable region by several times. Conversely, driving the magnon-like polariton mode only gives rise to normal bistability. This depends on whether the minimum driving power required to generate the bistability is non-monotonic with respect to the driving frequency. In addition, despite driving only the photon-like polariton mode, the photon- and magnon-like polariton modes can show simultaneous explosive growth of the bistability in microwave transmission, owing to the light-matter interaction. Our research sheds light on the hidden side of the nonlinear cavity magnonic system and provides a potential application for cavity spintronic devices founded on this novel feature.
