Parameterized families of toric code Hamiltonians realize em-duality pumping and higher-order anyon pumping, diagnosed by topological pumping into tensor-network bond spaces and corner modes.
A 2-form connection is defined in the space of open string field theory solutions, producing invariant higher holonomies and 3-form curvature potentially corresponding to the B-field.
Bosonic topological edge modes persist at the boundaries of an interacting ladder quantum paramagnet, visible in time-dependent spin correlations and dynamical structure factor computed via tensor networks, even when non-interacting theory breaks down.
