Fracton topological order represents a new type of topological quantum matter in three dimensions, with unusual properties such as quasiparticle excitations with restricted mobility and sub-extensive ground state degeneracy, all of which are impossible in more conventional topological ordered phases. Fracton models were discovered in search of self-correcting quantum memory. I will first discuss the connection between topological order and quantum error-correction code, and discuss the entanglement structure of gapped phases in general. I will then use entanglement renormalization to characterize fracton topological order that arise in Pauli stabilizer models.

Meng Cheng is an Assistant Professor of Physics at Yale University. He received his undergraduate degree from Nanjing University (China). In 2013, he obtained his Ph.D degree from the University of Maryland, College Park, where he studied topological superconductivity and its applications in quantum information processing. He then moved to a postdoctoral researcher position in Microsoft Research, Station Q in Santa Barbara, during which he investigated the interplay of global symmetry and topological quantum order. He joint the Department of Physics at Yale University in 2016.
