Matrix Product States for Modulated Topological Phases: Crystalline Equivalence Principle and Lieb-Schultz-Mattis Constraints
Shang-Qiang Ning, Hiromi Ebisu, Ho Tat Lam
Modulated symmetries are internal symmetries that act in a spatially non-uniform manner. Consequently, when a modulated symmetry is combined with a spatial symmetr…

When does a lattice higher-form symmetry flow to a topological higher-form symmetry at low energies?
Ruizhi Liu, Pok Man Tam, Ho Tat Lam +1
We study the lattice version of higher-form symmetries on tensor-product Hilbert spaces. Interestingly, at low energies, these symmetries may not flow to the topological higher-for…
