We describe a construction of topological orders from coupled lower dimensional symmetry-protected topological orders, which is closely related to gauging a subsystem symmetry. Our construction yields both conventional topological orders and exotic fracton topological orders of type-I and type-II. In particular, we find a coupled spin chain construction of Haah's cubic code, and a coupled layer construction of Yoshida's fractal spin liquids.

  1. String-Membrane-Nets from Higher-Form Gauging: An Alternate Route to $p$-String Condensation

    cond-mat.str-el 2025-05 conditional novelty 7.0 of 10

    Gauging a diagonal 1-form symmetry of stacked 2+1D topological orders implements p-string condensation, yielding 3+1D fracton phases such as the X-Cube and string-membrane-net models.
