Description:
Author(s): Jasmin Graf, Hannes Pfeifer, Florian Marquardt, and Silvia Viola Kusminskiy A unique feature of cavity optomagnonics is the possibility of coherently coupling light to spin excitations on top of magnetic textures. Here, the authors propose a cavity-optomagnonic system with a nonhomogeneous magnetic ground state, namely, a vortex in a magnetic microdisc. Using both analytical and computational methods, they study the cavity-enhanced coupling between optical whispering gallery modes and magnon modes, localized at the vortex. The results, both in terms of value and tunability of the coupling, point to the promise of engineered optomagnonic systems for quantum information platforms. [Phys. Rev.
