Robustness of three-dimensional fracton topological order

该项目旨在开发和研究基于量子物质拓扑相位的三维现实理论模型，用于容错、自校正拓扑保护的量子存储器。我们希望研究所谓的三维分形拓扑相的物理、鲁棒性和量子相变，并系统地寻找与潜在实验更密切联系的模型。从技术上讲，我们计划使用变分方法以及链接簇展开来理解外部扰动下分形拓扑秩序的分解。

This project aims to develop and examine realistic theoretical models in three dimensions based on topological phases of quantum matter for fault-tolerant, self-correcting topologically protected quantum memories. We want to investigate the physics, robustness and quantum phase transitions of three-dimensional so-called fracton topological phases and systematically search for models in closer contact with potential experiments. Technically, we plan to use variational approaches as well as linked-cluster expansions to understand the breakdown of fracton topological order under external perturbations.
