Anomalies of categorical symmetries
Carolyn Zhang, Clay Córdova
We present a general approach for detecting when a fusion category symmetry is anomalous, based on the existence of a special kind of Lagrangian algebra of the corresponding Drinfe…
Bulk-boundary correspondence for interacting Floquet systems in two dimensions
Carolyn Zhang, Michael Levin
We present a method for deriving bulk and edge invariants for interacting, many-body localized Floquet systems in two spatial dimensions. This method is based on a general mathemat…
Topological invariants for SPT entanglers
Carolyn Zhang
We develop a framework for classifying locality preserving unitaries (LPUs) with internal, unitary symmetries in dimensions, based on dimensional ``flux insertion opera…
Exactly solvable model for a deconfined quantum critical point in 1D
Carolyn Zhang, Michael Levin
We construct an exactly solvable lattice model for a deconfined quantum critical point (DQCP) in (1+1) dimensions. This DQCP occurs in an unusual setting, namely at the edge of a (…
Proposal for realizing anomalous Floquet insulators via Chern band annihilation
Carolyn Zhang, Tobias Holder, Netanel H. Lindner +2
Two-dimensional periodically driven systems can host an unconventional topological phase unattainable for equilibrium systems, termed the Anomalous Floquet-Anderson insulator (AFAI…
Vanishing Hall conductance for commuting Hamiltonians
Carolyn Zhang, Michael Levin, Sven Bachmann
We consider the process of flux insertion for ground states of almost local commuting projector Hamiltonians in two spatial dimensions. In the case of finite dimensional local Hilb…
