摘要:

研究了金属和超导互补开口环谐振器中与二维电子气回旋跃迁耦合的超强光-物质相互作用机制。亚波长光限制和回旋跃迁的大光学偶极矩产生高达$\frac{Ω_R}{ω_c}=$ 0.87的高归一化耦合率。我们观察到由于相互作用哈密顿量的抗磁项的两个极化激元的蓝移。

英文摘要:

The ultrastrong light-matter interaction regime was investigated in metallic and superconducting complementary split ring resonators coupled to the cyclotron transition of two dimensional electron gases. The sub-wavelength light confinement and the large optical dipole moment of the cyclotron transition yield record high normalized coupling rates of up to $\frac{Ω_R}{ω_c}=$ 0.87. We observed a blue-shift of both polaritons due to the diamagnetic term of the interaction Hamiltonian.
