论文摘要
实现强耦合的能力使腔体磁系统成为开发混合量子系统和对物理基本问题的调查的令人兴奋的平台。不幸的是，当前的实验实现被限制在单个频率下运行，这是由微波腔的几何形状定义的。在本文中，我们意识到一个高度可调的，低温的微波腔与磁自旋强烈耦合。该腔体可以原位调节多达1.5 GHz，约占其原始10 GHz共振频率的15％。此外，该系统在所有频率的强耦合方案中保持范围，其合作性约为800。
The ability to achieve strong-coupling has made cavity-magnon systems an exciting platform for the development of hybrid quantum systems and the investigation of fundamental problems in physics. Unfortunately, current experimental realizations are constrained to operate at a single frequency, defined by the geometry of the microwave cavity. In this article we realize a highly-tunable, cryogenic, microwave cavity strongly coupled to magnetic spins. The cavity can be tuned in situ by up to 1.5 GHz, approximately 15% of its original 10 GHz resonance frequency. Moreover, this system remains within the strong-coupling regime at all frequencies with a cooperativity of approximately 800.
