AI 中文摘要
超冷偶极混合物处于依赖于组分的光学势中,是研究组分内和组分间各向异性长程相互作用相互影响的有趣平台。我们研究了处于反魔波长配置的分隔双层中的二元偶极混合物这一特殊情况。通过结合二阶微扰理论和团簇 - 古兹维勒计算,揭示了两种组分可能的丰富晶相图景,表明通过超交换,位点间跳跃可能导致不同晶相之间的固 - 固转变。这些晶相及相应转变可用如光学晶格中的镧系混合物通过实验实现。
英文摘要
Ultra-cold dipolar mixtures in component-dependent optical potentials constitute an interesting platform for the study of the interplay between intra- and inter-component anisotropic long-range interactions. We study the particular case of binary dipolar mixtures placed in separated bilayers which are displaced in an anti-magic wavelength configuration. Using a combination of second-order perturbation theory and cluster-Gutzwiller calculations, we unveil a rich landscape of possible crystalline phases for the two components, showing that, interestingly, inter-site hopping may result, via super-exchange, in solid-into-solid transitions between different crystalline phases. These crystalline phases and the corresponding transitions can be experimentally realized using e.g. lanthanide mixtures in optical lattices.
