A Classifying Space for Phases of Matrix Product States
Daniel D. Spiegel, Marvin Qi, David T. Stephen +3
We construct a topological space consisting of translation invariant injective matrix product states (MPS) of all physical and bond dimensions and show that it has th…

Excitation-detector principle and the algebraic theory of planon-only abelian fracton orders
Evan Wickenden, Wilbur Shirley, Agnès Beaudry +1
We study abelian planon-only fracton orders: a class of three-dimensional (3d) gapped quantum phases in which all fractional excitations are abelian particles restricted to move in…

Generalized symmetries in singularity-free nonlinear models and their disordered phases
Salvatore D. Pace, Chenchang Zhu, Agnès Beaudry +1
We study the nonlinear -model in -dimensional spacetime with connected target space and show that, at energy scales below singular field configurations (such as vo…
