Disentangling the Toric Code
Lei Gioia, Salvatore D. Pace, Ruben Verresen +2
Commuting-projector Hamiltonians with integer spectrum such as the 1+1d Ising ferromagnet and the 2+1d toric code may be regarded as the generators of non-on-site symmetries…
Lattice 2-group symmetries: operators, defects, and gauging
Lucas Z. Brito, Salvatore D. Pace
We construct and study lattice realizations of finite 2-group symmetries in d quantum lattice systems with finite-dimensional tensor-product Hilbert spaces. We focus on two…
Infinite-Order Lattice Chiral Anomalies and CPT
Elijah Lew-Smith, Salvatore D. Pace, Shu-Heng Shao
A key property of a global symmetry's anomaly is its order: the smallest integer for which the diagonal symmetry of the -copy system is anomaly-free. While many familiar lat…
Lieb-Schultz-Mattis constraints from stratified anomalies of modulated symmetries
Salvatore D. Pace, Daniel Bulmash
We introduce stratified symmetry operators and stratified anomalies in quantum lattice systems as generalizations of onsite symmetry operators and onsite projective representations…
