论文摘要
光子频率$（ω）$ - 动量$（q）$分散的概念已在人工介电结构（例如光子晶体和超材料）中进行了广泛的研究。但是，在原子水平上以天然材料托管的电动力激发的$ω-q $分散率要小得多。在这里，我们开发了麦克斯韦汉密尔顿物质理论，并结合了原子极化的量子理论，以获得与光子场相互作用的天然材料的电动力分散体。我们将该理论应用于硅，并发现异常原子波的存在。这些波发生在宏观理论中通常禁止传播波的光谱区域。我们的发现表明，自然培养基可以在Pico-Photonics制度中拥有各种尚未发现的有效波长的尚未发现的波。
The concept of photonic frequency $(ω)$ - momentum $(q)$ dispersion has been extensively studied in artificial dielectric structures such as photonic crystals and metamaterials. However, the $ω-q$ dispersion of electrodynamic excitations hosted in natural materials at the atomistic level is far less explored. Here, we develop a Maxwell Hamiltonian theory of matter combined with the quantum theory of atomistic polarization to obtain the electrodynamic dispersion of natural materials interacting with the photon field. We apply this theory to silicon and discover the existence of anomalous atomistic waves. These waves occur in the spectral region where propagating waves are conventionally forbidden in a macroscopic theory. Our findings demonstrate that natural media can host a variety of yet to be discovered waves with sub-nano-meter effective wavelengths in the pico-photonics regime.
