Circulating cavity magnon polaritons
Weichao Yu, Tao Yu, Gerrit E. W. Bauer
We predict magnon polariton states circulating unidirectionally in a microwave cavity when loaded by a number of magnets on special lines. Realistic finite-element numerical simula…
Magnon Trap by Chiral Spin Pumping
Tao Yu, Hanchen Wang, Michael A. Sentef +2
Chiral spin pumping is the generation of a unidirectional spin current in half of ferromagnetic films or conductors by dynamic dipolar stray fields from close-by nanomagnets. We fo…
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…
Non-Contact Spin Pumping by Microwave Evanescent Fields
Tao Yu, Gerrit E. W. Bauer
The angular momentum of evanescent light fields has been studied in nano-optics and plasmonics, but not in the microwave regime. Here we predict non-contact pumping of electron spi…
Chiral Pumping of Spin Waves
Tao Yu, Yaroslav M. Blanter, Gerrit E. W. Bauer
We report a theory for the coherent and incoherent chiral pumping of spin waves into thin magnetic films through the dipolar coupling with a local magnetic transducer, such as a na…
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…
