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…
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…
Unveiling a Pump-Induced Magnon Mode via its Strong Interaction with Walker Modes
J. W. Rao, Bimu Yao, C. Y. Wang +3
We observe a power-dependent anticrossing of Walker spin-wave modes under microwave pumping when a ferrimagnet is placed in a microwave waveguide that does not support any discrete…
Coherent and Dissipative Cavity Magnonics
Michael Harder, Bimu Yao, Yongsheng Gui +1
Strong interactions between magnetic materials and electrodynamic cavities mix together spin and photon properties, producing unique hybridized behaviour. The study of such coupled…
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…
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…
Microscopic mechanism of level attraction
Bimu Yao, Tao Yu, Xiang Zhang +4
The emerging level attraction from dissipative light-matter coupling converges the typical Rabi-splitting feature from coherent coupling and exhibits potentials in topological info…
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…
Theory and experiment on cavity magnon polariton in the 1D configuration
B. M. Yao, Y. S. Gui, Y. Xiao +5
We have theoretically and experimentally investigated the dispersion of the cavity-magnon-polariton (CMP) in a 1D configuration, created by inserting a low damping magnetic insulat…

B. M. Yao, L. Fu, X. S. Chen +4
A technique for rapidly detecting microwave phase has been developed which uses a spintronic device that can directly rectify microwave fields into a dc voltage signal. Use of a vo…
