空间扩展激发的分形物理

Fracton physics of spatially extended excitations

Meng-Yuan Li, Peng Ye

摘要:

分形拓扑序承载了细分的点状激发(例如,fracton)具有受限的移动性。在这篇文章中,我们将探讨更奇怪的实现分形相位,承认空间扩展的激励与限制的流动性和变形性。首先,我们提出了精确可解的格点量子阻挫自旋模型,并解析地研究了它们的基态和激发态。我们构建了一个家谱,其中父模型和后代模型共享激励DNA。其次,借助这些模型的可解性和新的激发谱,我们开始了对空间扩展激发的定量和定性性质的一般性讨论的第一步,其流动性和变形性在一定程度上受到限制。特别是,作为一个有用的观点来理解这样的分形物理学,所有的激发被分为四个相互不同的部门,即,简单的激发,复杂的激发,本质上断开的激发,和平凡的激发。一些影响,例如,简要讨论了凝聚态物理和引力。

英文摘要:

Fracton topological order hosts fractionalized point-like excitations (e.g., fractons) that have restricted mobility. In this article, we explore even more bizarre realization of fracton phases that admit spatially extended excitations with restriction on both mobility and deformability. First, we present exactly solvable lattice quantum frustrated spin models and study their ground states and excited states analytically. We construct a family tree in which parent models and descendent models share excitation DNA. Second, with the help of solvability and novel excitation spectrum of these models, we initiate the first-step of general discussions on quantitative and qualitative properties of spatially extended excitations whose mobility and deformability are restricted to some extent. Especially, as a useful viewpoint for understanding such fracton-physics, all excitations are divided into four mutually distinct sectors, namely, simple excitations, complex excitations, intrinsically disconnected excitations, and trivial excitations. Several implications in, e.g., condensed matter physics and gravity are briefly discussed.
