论文摘要
我们计算半合成三维构型中偶极相互作用的超低分子或rydberg原子的性能 - 一种合成尺寸以及二维真实空间光学晶格或周期性微晶状体阵列 - 使用STOCHASTIC GREEN绿色功能量子量子量子carlo carlo方法。通过计算热力学量和适当的相关函数以及它们的有限尺寸尺度，我们表明，在低温阶段有二阶过渡到低温阶段，在该阶段中，分子或rydberg原子的内部旋转状态或电子状态的合成态中的二维“床单”形式。相互作用$ V $的不同值的模拟，这些$ V $在真实和合成空间中相邻的原子或分子之间作用，使我们能够计算一个相图。我们在足够大的$ V $和量子相转换时发现有限的温度过渡 - 关键值$ v_c $以下过渡温度消失。
We calculate properties of dipolar interacting ultracold molecules or Rydberg atoms in a semi-synthetic three-dimensional configuration -- one synthetic dimension plus a two-dimensional real space optical lattice or periodic microtrap array -- using the stochastic Green function Quantum Monte Carlo method. Through a calculation of thermodynamic quantities and appropriate correlation functions, along with their finite size scalings, we show that there is a second order transition to a low temperature phase in which two-dimensional `sheets' form in the synthetic dimension of internal rotational or electronic states of the molecules or Rydberg atoms, respectively. Simulations for different values of the interaction $V$, which acts between atoms or molecules that are adjacent both in real and synthetic space, allow us to compute a phase diagram. We find a finite-temperature transition at sufficiently large $V$, as well as a quantum phase transition -- a critical value $V_c$ below which the transition temperature vanishes.
