Angular Momentum Conservation and Phonon Spin in Magnetic Insulators
Andreas Rückriegel, Simon Streib, Gerrit E. W. Bauer +1
We develop a microscopic theory of spin-lattice interactions in magnetic insulators, separating rigid-body rotations and the internal angular momentum, or spin, of the phonons, whi…
Coherent pumping of high momentum magnons by light
Fran Šimić, Sanchar Sharma, Yaroslav M. Blanter +1
We propose to excite a large number of coherent magnons with high momentum in optical cavities. This is achieved by two counterpropagating optical modes that are detuned by the fre…
Resources of nonlinear cavity magnonics for quantum information
Mehrdad Elyasi, Yaroslav M. Blanter, Gerrit E. W. Bauer
We theoretically explore nonlinearities of ferromagnets in microwave cavities in the classical and quantum regimes, and assess the resources for quantum information, i.e. fluctuati…
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…
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…
