论文摘要
我们提出了在光频率下具有强磁反应的新型量子天线和超材料。我们的设计基于天然原子的排列,只有电偶极转换矩的距离小于光波长,但比其物理尺寸大得多。特别是,我们表明原子二聚体可以在其反对称模式下用作磁性天线,以提高其附近磁性转变的衰减速率,从而提高几个数量级。此外,我们研究由有或没有空腔的原子双层组成的跨膜,并表明它们可以完全反射光的电场和磁场,从而形成几乎完美的电气/磁性镜。拟议的量子超材料可以使用可用的最先进技术制造,并在经典光学和量子工程中保证几种应用。
We propose novel quantum antennas and metamaterials with strong magnetic response at optical frequencies. Our design is based on the arrangement of natural atoms with only electric dipole transition moments at distances smaller than a wavelength of light but much larger than their physical size. In particular, we show that an atomic dimer can serve as a magnetic antenna at its antisymmetric mode to enhance the decay rate of a magnetic transition in its vicinity by several orders of magnitude. Furthermore, we study metasurfaces composed of atomic bilayers with and without cavities and show that they can fully reflect the electric and magnetic fields of light, thus, forming nearly perfect electric/magnetic mirrors. The proposed quantum metamaterials can be fabricated with available state-of-the-art technologies and promise several applications both in classical optics and quantum engineering.
