得益于量子信息理论的发展,保真度、纠缠熵等概念被引入到量子相变的研究中,不仅能用来标识新奇的物质相,还能用来探测量子相变的临界点以及描绘其临界行为.从度量空间的角度来看,这些物理量都可以被理解为度量空间中两个函数的距离.本文利用波函数和实空间中密度分布函数的距离,研究了以广义Aubry-André-Harper模型为代表的准周期系统,发现该方法不仅能标识拓展相、临界相和局域相,还能找到准确的相变点并计算出临界指数.此外,不仅将度量空间方法推广到波包扩散动力学研究,还提出了一种新的量,即态密度分布函数的距离,发现上述定义的两种物理量都能标识不同的物质相及相变点.通过定义某个函数在不同参数下的距离,不仅为标识已知系统相变点提供了研究工具,还为探测未知系统的不同物质相、相变点及其临界行为提供了一种直观的方法.
