Bifurcating entanglement-renormalization group flows of fracton stabilizer models

Arpit Dua, Pratyush Sarkar, Dominic J. Williamson +1

We investigate the entanglement-renormalization group flows of translation-invariant topological stabilizer models in three dimensions. Fracton models are observed to bifurcate und…

Generalized Lieb-Schultz-Mattis theorem on bosonic symmetry protected topological phases

Shenghan Jiang, Meng Cheng, Yang Qi +1

We propose and prove a family of generalized Lieb-Schultz-Mattis (LSM) theorems for symmetry protected topological (SPT) phases on boson/spin models in any dimensions. The "convent…

Relative Anomalies in (2+1)D Symmetry Enriched Topological States

Maissam Barkeshli, Meng Cheng

Certain patterns of symmetry fractionalization in topologically ordered phases of matter are anomalous, in the sense that they can only occur at the surface of a higher dimensional…

Fractionalization and Anomalies in Symmetry-Enriched U(1) Gauge Theories

Shang-Qiang Ning, Liujun Zou, Meng Cheng

We classify symmetry fractionalization and anomalies in a (3+1)d U(1) gauge theory enriched by a global symmetry group . We find that, in general, a symmetry-enrichment pattern…

Interacting Edge States of Fermionic Symmetry-Protected Topological Phases in Two Dimensions

Joseph Sullivan, Meng Cheng

Recently, it has been found that there exist symmetry-protected topological phases of fermions, which have no realizations in non-interacting fermionic systems or bosonic models. W…

Compactifying fracton stabilizer models

Arpit Dua, Dominic J. Williamson, Jeongwan Haah +1

We investigate two dimensional compactifications of three dimensional fractonic stabilizer models. We find the two dimensional topological phases produced as a function of compacti…
