Yu, T. (author), Zhang, Xiang (author), Sharma, S. (author), Blanter, Y.M. (author), Bauer, G.E. (author) We theoretically investigate the collective excitations of multiple (sub)millimeter-sized ferromagnets mediated by waveguide photons. By the position of the magnets in the waveguide, the magnon-photon coupling can be tuned to be chiral, i.e., magnons only couple with photons propagating in one direction, leading to an asymmetric transfer of...
