Highly Tunable Photon-Magnon Coupling Governed by Collective-Mode Profiles in Reconfigurable Dielectric-Resonator Arrays
Shihao Zhou, Edward Kwao, Junming Wu +7
The spatial structure of a microwave photon mode provides a degree of freedom for controlling its interaction with a localized magnetic excitation. We demonstrate site-selective ma…
Modulating Surface Acoustic Wave Generation through Superconductivity
Andrew Christy, Yuzan Xiong, Rui Sun +11
Surface acoustic waves (SAWs), with their five orders-of-magnitude slower propagation velocity, allow for considerably shorter wavelengths at the same frequency compared to electro…
Multimode magnon-phonon cavity driven by symmetry-locked strain fields
Chunli Tang, Yujie Zhu, Dayne Sasaki +13
Hybrid magnon-phonon cavities with precise control knobs are highly sought after for coherent energy and signal transduction in solid-state platforms. While strain offers a powerfu…
Tuning Magneto-Optical Zero-Reflection via Dual-Channel Hybrid Magnonics
Andrew Christy, Yujie Zhu, Yi Li +7
Multi-channel coupling in hybrid systems makes an attractive testbed not only because of the distinct advantages entailed in each constituent mode, but also the opportunity to leve…
Pump-induced magnon anticrossing due to three-magnon splitting and confluence
Tao Qu, Yuzan Xiong, Xufeng Zhang +2
We present a plausible mechanism for achieving magnon-magnon level repulsion spectrum originating from the oscillation between the splitting and confluence in a three-magnon scatte…
Hybrid Magnonics with Localized Spoof Surface Plasmon Polaritons
Yuzan Xiong, Andrew Christy, Zixin Yan +8
Hybrid magnonic systems have emerged as a promising direction for information propagation with preserved coherence. Due to high tunability of magnons, their interactions with micro…
Combinatorial split-ring and spiral meta-resonator for efficient magnon-photon coupling
Yuzan Xiong, Andrew Christy, Yun Dong +6
Developing hybrid materials and structures for electromagnetic wave engineering has been a promising route towards novel functionalities and tunabilities in many modern application…
Magnon-Photon Coupling in an Opto-Electro-Magnonic Oscillator
Yuzan Xiong, Jayakrishnan M. P. Nair, Andrew Christy +5
The opto-electronic oscillators (OEOs) hosting self-sustained oscillations by a time delayed mechanism are of particular interest in long-haul signal transmission and processing. O…
Strong magnon-magnon coupling in an ultralow damping all-magnetic-insulator heterostructure
Jiacheng Liu, Yuzan Xiong, Jingming Liang +12
Magnetic insulators such as yttrium iron garnets (YIGs) are of paramount importance for spin-wave or magnonic devices as their ultralow damping enables ultralow power dissipation t…
