我们研究微波屏蔽极性分子间的偶极相互作用如何随相互作用强度变化，构建自束缚液滴的结构。我们确定液滴到晶体的转变为有限尺寸一阶相变；还预测晶体相和液滴相分别存在液滴环态和过渡超固态等额外结构。为描述这一强关联区域，尤其是量子基态的重构，我们设计了基于神经量子态的变分蒙特卡洛框架，该框架特别适合描述基态及构型差异极大的近简并态，且可便捷确定超流分数。我们的结果揭示了偶极相互作用将分子液滴重组为晶体的一系列有限尺寸结构。
英文摘要
We investigate how dipolar interactions between microwave-shielded polar molecules structure the self-bound droplets formed under variation of the interaction strength. We identify the transition from droplets to crystals as a finite-size first order transition. With droplet-ring states and transitional supersolid states we predict additional structure in the crystal and droplet phases, respectively. To describe this strongly correlated regime, and in particular the reconfiguration of quantum ground states, we design a variational Monte Carlo framework based on neural quantum states. It is especially suitable to describe ground states and almost degenerate states with very different configurations. Moreover, one can easily determine the superfluid fraction. Our results reveal the sequence of finite-size structures through which dipolar interactions reorganize molecular droplets into crystals.
