摘要翻译:
我们给出了一个推广的Feynman-Kikuchi模型的量子蒙特卡罗模拟,其中包括空位和交换粒子之间相互作用的可能性。通过测量缠绕数(超流密度)和密度结构因子,确定了相图,并表明该相图呈现出既有超流有序又有电荷有序的区域。

英文摘要:
  We present Quantum Monte Carlo simulations of a generalization of the Feynman-Kikuchi model which includes the possibility of vacancies and interactions between the particles undergoing exchange. By measuring the winding number (superfluid density) and density structure factor, we determine the phase diagram, and show that it exhibits regions which possess both superfluid and charge ordering.
