Giant Enhancement of Magnonic Frequency Combs by Exceptional Points
Congyi Wang, Jinwei Rao, Zhijian Chen +6
With their incomparable time-frequency accuracy, frequency combs have significantly advanced precision spectroscopy, ultra-sensitive detection, and atomic clocks. Traditional metho…
Meter-scale strong coupling between magnons and photons
Jinwei Rao, C. Y. Wang, Bimu Yao +3
We experimentally realize a meter-scale strong coupling effect between magnons and photons at room temperature, with a coherent coupling of 20 m and a dissipative coupling of 7.6 m…
Coherent Microwave Emission of a Gain-Driven Polariton
Bimu Yao, Y. S. Gui, J. W. Rao +3
By developing a gain-embedded cavity magnonics platform, we create gain-driven polariton (GDP) that is activated by an amplified electromagnetic field. Distinct effects of gain-dri…
Control of the magnon-polariton hybridization with a microwave pump
C. Zhang, Jinwei Rao, C. Y. Wang +5
Pump-induced magnon modes (PIMs) are recently discovered elementary excitations in ferrimagnets that offer significant tunability to spin dynamics. Here, we investigate the couplin…
Unconventional Singularity in Anti-Parity-Time Symmetric Cavity Magnonics
Y. Yang, Yi-Pu Wang, J. W. Rao +4
By engineering an anti-parity-time (anti-PT) symmetric cavity magnonics system with precise eigenspace controllability, we observe two different singularities in the same system. O…
Electrical detection of magnon-photon interaction via auxiliary spin wave mode
Peng-Chao Xu, J. W. Rao, Y. Wang +4
We report on the electrical detection of a hybrid magnon-photon system, which is comprised of a magnetic sample coupled to a planar cavity. While the uniform Kittel mode has the la…
Travelling photons mediated interactions between a magnon mode and a cavity photon mode
J. W. Rao, Y. P. Wang, Y. Yang +5
We systematically study the indirect interaction between a magnon mode and a cavity photon mode mediated by travelling photons of a waveguide. From a general Hamiltonian, we derive…
Nonreciprocity and Unidirectional Invisibility in Cavity Magnonics
Yi-Pu Wang, J. W. Rao, Y. Yang +5
We reveal the cooperative effect of coherent and dissipative magnon-photon couplings in an open cavity magnonic system, which leads to nonreciprocity with a considerably large isol…
Cavity mediated dissipative coupling of distant magnetic moments: theory and experiment
Peng-Chao Xu, J. W. Rao, Y. S. Gui +2
We investigate long-range coherent and dissipative coupling between two spatially separated magnets while both are coupled to a microwave cavity. A careful examination of the syste…
Coherent control of magnon radiative damping with local photon states
B. M. Yao, T. Yu, Y. S. Gui +4
The collective excitation of ordered spins, known as spin waves or magnons, can in principle radiate by emitting travelling photons to an open system when decaying to the ground st…
Control of the magnon-photon level attraction in a planar cavity
Y. Yang, J. W. Rao, Y. S. Gui +3
A resistive coupling circuit is used to model the recently discovered dissipative coupling in a hybridized cavity photon-magnon system. With this model as a basis we have designed…
Level Attraction Due to Dissipative Magnon-Photon Coupling
M. Harder, Y. Yang, B. M. Yao +5
We report dissipative magnon-photon coupling caused by cavity Lenz effect, where the magnons in a magnet induce a rf current in the cavity, leading to a cavity back action that imp…
