论文摘要
我们提出了二维量子近晶体及其亲戚的量规理论,这是由于它们在相关量子物质中的实现而动机。该描述给出了对声子和拓扑缺陷的统一处理,分别用一对耦合量规场和相应的电荷编码。这些电荷表现出差异的量子动力学,异常慢的高度各向异性扩散在脊椎动物内部。这种方法对二维相称的晶体(通过不一致的晶体 - 超酚类)的多阶段量子熔化过渡透明地描述成量子晶状体,随后将其融化成量子性nematium nematic nematic和sosotropic的超级流体,所有这些都以higgs the Higgs Transitions的顺序进行。
We present a gauge theory formulation of a two-dimensional quantum smectic and its relatives, motivated by their realizations in correlated quantum matter. The description gives a unified treatment of phonons and topological defects, respectively encoded in a pair of coupled gauge fields and corresponding charges. The charges exhibit subdimensional constrained quantum dynamics and anomalously slow highly anisotropic diffusion of disclinations inside a smectic. This approach gives a transparent description of a multi-stage quantum melting transition of a two-dimensional commensurate crystal (through an incommensurate crystal - a supersolid) into a quantum smectic, that subsequently melts into a quantum nematic and isotropic superfluids, all in terms of a sequence of Higgs transitions.
