论文摘要
我们研究了有限温度自旋密度波（SDW）和电荷密度波（CDW）在Mott-Mundiculator极限的光学晶格中的两个组件晶状体纺纱杆气体的过渡。在温度尺度上，在现场相互作用能量的一半左右，我们发现新的临界状态出现，特别是与有限温度SDW-CDW，均匀的SDW和均匀的CDW过渡相关的新的双层线和两条临界线。直接计算缩放行为的临界指数并在此关键制度中调查有效理论表明它们属于五维ISING普遍性类别，清楚地表明了系统相互作用的远程特征。我们可以通过在中间温度尺度上进行的当前实验设置很容易观察到我们对新兴临界的预测。
We investigate the finite temperature spin density wave (SDW) and charge density wave (CDW) transition of two-component lattice spinor Bose gases in optical lattices in the Mott-insulator limit. At the temperature scale around half of the on-site interaction energy, we find a new critical regime emerges and features, in particular, a new bicritical line and two critical lines associated with the finite temperature SDW-CDW, homogeneous-SDW, and homogeneous-CDW transition, respectively. Direct calculation of the critical exponents for the scaling behavior and investigating on the effective theory in this critical regime show that they belong to the five-dimensional Ising universality class, clearly manifesting the long-range character of the system's interaction. Our prediction of the emergent criticality can be readily observed by current experimental setups operated at the intermediate temperature scale around half the on-site interaction energy.
