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…
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…
Optimal mode matching in cavity optomagnonics
Sanchar Sharma, Babak Zare Rameshti, Yaroslav M. Blanter +1
Inelastic scattering of photons is a promising technique to manipulate magnons but it suffers from weak intrinsic coupling. We theoretically discuss an idea to increase optomagnoni…
Surface dynamics of rough magnetic films
Tao Yu, Sanchar Sharma, Yaroslav M. Blanter +1
The chirality of Damon-Eshbach (DE) magnons affects the transport of energy and angular momentum at the surface of magnetic films and spheres. We calculate the surface-disorder-lim…
