Spin-Wave Doppler Shift by Magnon Drag in Magnetic Insulators
Tao Yu, Chen Wang, Michael A. Sentef +1
The Doppler shift of the quasiparticle dispersion by charge currents is responsible for the critical supercurrents in superconductors and instabilities of the magnetic ground state…
Optical Manipulation of Domains in Chiral Topological Superconductors
Tao Yu, Martin Claassen, Dante M. Kennes +1
Optical control of chirality in chiral superconductors bears potential for future topological quantum computing applications. When a chiral domain is written and erased by a laser…
Nonreciprocal surface magnetoelastic dynamics
Tao Yu
Motivated by recent experiments, we investigate the nonreciprocal magnetoelastic interaction between the surface acoustic phonons of dielectric non-magnetic substrates and magnons…
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…
Non-Hermitian coherent coupling of nanomagnets by exchange spin waves
Hanchen Wang, Jilei Chen, Tao Yu +16
Non-Hermitian physics has recently attracted much attention in optics and photonics. Less explored is non-Hermitian magnonics that provides opportunities to take advantage of the i…
Magnetic resonance imaging of spin-wave transport and interference in a magnetic insulator
Iacopo Bertelli, Joris J. Carmiggelt, Tao Yu +6
Spin waves - the elementary excitations of magnetic materials - are prime candidate signal carriers for low dissipation information processing. Being able to image coherent spin-wa…
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 Coupling to Magnetodipolar Radiation
Tao Yu, Gerrit E. W. Bauer
We review and extend the theory of chiral pumping of spin waves by magnetodipolar stray fields that generate unidirectional spin currents and asymmetric magnon densities. We illust…
