论文摘要
我们为在两个维度和三个维度的量子点中提供了广泛的新的直接路径蒙特蒙特卡洛结果。这使我们能够研究系统的非经典旋转惯性（NCRI），并发现了异常的负超氟漏洞分数[Phys。莱特牧师。在某些条件下，112，235301（2014）]。此外，我们通过计算复杂的中心两个粒子相关函数来研究结构特性。值得注意的是，我们发现空间结构与NCRI之间没有联系，因为前者在超级流体分数朝着负无穷大的参数方面几乎相同。
We present extensive new direct path-integral Monte Carlo results for electrons in quantum dots in two and three dimensions. This allows us to investigate the nonclassical rotational inertia (NCRI) of the system, and we find an abnormal negative superfluid fraction [Phys. Rev. Lett. 112, 235301 (2014)] under some conditions. In addition, we study the structural properties by computing a sophisticated center-two particle correlation function. Remarkably, we find no connection between the spatial structure and the NCRI, since the former can be nearly identical for Fermi- and Bose-statistics for parameters where the superfluid fraction is diverging towards negative infinity.
