(TU Delft QN/Bauer Group; Kavli institute of nanoscience Delft; Tohoku University) Date 2018 Abstract The interaction between two magnetic spheres in microwave cavities is studied by Mie scattering theory beyond the magnetostatic and rotating wave approximations. We demonstrate that two spatially separated dielectric and magnetic spheres can be strongly coupled over a long distance by the electric field component of standing microwave cavity modes. The interactions split acoustical (dark) and optical (bright) modes in a way that can be mapped on a molecular orbital theory of the hydrogen molecule. Breaking the symmetry by assigning different radii to the two spheres introduces "ionic" character to the magnonic bonds. These results illustrate the coherent and controlled energy exchange between objects in microwave cavities.
