基于群上同调的全息态复杂度

Holographic State Complexity from Group Cohomology

Bartlomiej Czech

摘要:

物质的拓扑相经常用一个额外维度的辅助系统来描述。我回顾了一维团簇态--具有对称性保护拓扑(SPT)序的最简单的量子态--作为全息对偶的玩具模型,并检查它以寻找定义全息复杂性的线索。群上同调,分类SPT订单,是一个可行的候选人的规范/引力对偶的复杂性的一个强大的定义。

英文摘要:

Topological phases of matter are often described using auxiliary systems in one extra dimension. I review the one-dimensional cluster state--the simplest quantum state with Symmetry-Protected Topological (SPT) order--as a toy model of holographic duality, and inspect it for clues about defining holographic complexity. Group cohomology, which classifies SPT orders, is a viable candidate for a robust definition of complexity in gauge/gravity duality.
