Design of an optomagnonic crystal: towards optimal magnon-photon mode matching at the microscale

Jasmin Graf, Sanchar Sharma, Hans Huebl +1

We put forward the concept of an optomagnonic crystal: a periodically patterned structure at the microscale based on a magnetic dielectric, which can co-localize magnon and photon…

Spin cat states in a ferromagnetic insulator

Sanchar Sharma, Victor A. S. V. Bittencourt, Alexy D. Karenowska +1

Generating non-classical states in macroscopic systems is a long standing challenge. A promising platform in the context of this quest are novel hybrid systems based on magnetic di…

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…
