摘要：

We experimentally demonstrate magnon polaritons with ultrastrong coupling and directional nonreciprocity in a metamolecule lacking time-reversal and space-inversion symmetries at room temperature. These experimental results are reproduced well via numerical simulations and theoretical considerations. Ultrastrong coupling is due to a direct interaction of magnons in the magnetic meta-atom with microwave photons confined in the chiral meta-atom as a resonator. Our results reveal a crucial step in identifying deep strongly coupled and optically moving magnon polaritons for hybrid quantum systems, synthetic gauge fields, and quasiparticle "chemistry" using metamaterials.
