论文摘要
我们系统地研究了地面相图和通过使用群集gutzwiller均值场方法在合成维度中对二维两种型骨系统的分解效应。我们的结果表明，当两种物种之间的交换间对称性破裂时，相图中超级畅通无阻状态的区域每当打开或关闭现场对跳跃期间时都会显着缩小。出乎意料的是，在我们以前的工作\ citetext {z中预测的非全能莫特阶段和分子超流相。 Lin等人，\ textColor {blue} {phys。莱特牧师。 \ textbf {125}，245301（2020）}}只能在这样的系统中存在，以至于对跳跃术语打开，更重要的是，其交换对称性必须损坏。此外，还研究了具有合成对跳跃相互作用的两个组分骨系统的解混合效应，并且我们发现，当当现场排斥相互作用的强度足够大时，系统中形成了不完全的分解状态。
We systematically study the ground-state phase diagrams and the demixing effect of a two-dimensional two-component bosonic system with pair hopping in synthetic dimension by using the cluster Gutzwiller mean-field method. Our results show that when the interexchange symmetry between the two species is broken, the regions of the super-counter-fluidity state in the phase diagram are dramatically shrunk whenever the on-site pair hopping term is turned on or off. Unexpectedly, the non-integer Mott phase and the molecular superfluid phase predicted in our previous work \citetext{Z. Lin et al., \textcolor{blue}{Phys. Rev. Lett. \textbf{125}, 245301 (2020)}}, can only exist in such a system that the pair hopping term is opened, and more importantly, its interexchange symmetry must be broken. Moreover, the demixing effect of the two-component bosonic system with synthetic pair hopping interaction has also been studied, and we find that an incompletely demixed state is formed in the system when the strength of the interspecies on-site repulsive interaction is sufficiently large.
