Unidirectional Pumping of Phonons by Magnetization Dynamics
Xiang Zhang, Gerrit E. W. Bauer, Tao Yu
We propose a method to control surface phonon transport by weak magnetic fields based on the pumping of surface acoustic waves (SAWs) by magnetostriction. We predict that the magne…
Chiral coupling of magnons in waveguides
Tao Yu, Xiang Zhang, Sanchar Sharma +2
We theoretically investigate the collective excitation of multiple (sub)millimeter-sized ferromagnets mediated by waveguide photons. By the position of the magnets in the waveguide…
Magnon Accumulation in Chirally Coupled Magnets
Tao Yu, Yu-Xiang Zhang, Sanchar Sharma +2
We report strong chiral coupling between magnons and photons in microwave waveguides that contain chains of small magnets on special lines. Large magnon accumulations at one edge o…
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…
