Bosonic Crystalline Symmetry Protected Topological Phases Beyond the Group Cohomology Proposal
Hao Song, Charles Zhaoxi Xiong, Sheng-Jie Huang
It is demonstrated by explicit construction that three-dimensional bosonic crystalline symmetry protected topological (cSPT) phases are classified by $H_ϕ^{5}(G;\mathbb{Z})\oplus H…
Cage-Net Fracton Models
Abhinav Prem, Sheng-Jie Huang, Hao Song +1
We introduce a class of gapped three-dimensional models, dubbed "cage-net fracton models," which host immobile fracton excitations in addition to non-Abelian particles with restric…
Twisted Fracton Models in Three Dimensions
Hao Song, Abhinav Prem, Sheng-Jie Huang +1
We study novel three-dimensional gapped quantum phases of matter which support quasiparticles with restricted mobility, including immobile "fracton" excitations. So far, most exist…
Building crystalline topological phases from lower-dimensional states
Sheng-Jie Huang, Hao Song, Yi-Ping Huang +1
We study the classification of symmetry protected topological (SPT) phases with crystalline symmetry (cSPT phases). Focusing on bosonic cSPT phases in two and three dimensions, we…
