Title: 光在固体透明基质中的杂质引起的安德森局域化

Abstract: A solid transparent medium with randomly positioned, immobile impurity atoms is a promising candidate for observation of Anderson localization of light in three dimensions. It can have low losses and allows for mitigation of the detrimental effect of longitudinal optical fields by an external magnetic field, but it has its own issues: thermal oscillations of atoms around their equilibrium positions and inhomogeneous broadening of atomic spectral lines due to random local electric fields. Our calculations suggest that these complications should not impede observation of Anderson localization of light in such materials provided that sufficiently high number densities of impurities can be reached. The thermal oscillations hardly affect light propagation whereas the inhomogeneous broadening can be compensated for by increasing the number density of impurities. Show Chinese abstract

Abstract: 一种具有随机定位的不可移动杂质原子的固体透明介质是观察三维光安德森局域化的有前途的候选材料。 它可以具有低损耗，并且可以通过外部磁场减轻纵向光学场的有害影响，但它自身存在问题：原子在其平衡位置周围的热振动以及由于随机局部电场导致的原子谱线的不均匀加宽。 我们的计算表明，只要能够达到足够高的杂质密度，这些复杂因素不应阻碍在这些材料中观察光的安德森局域化。 热振动几乎不影响光的传播，而通过增加杂质的密度可以补偿不均匀加宽。
