Fate of Bosonic Topological Edge Modes in the Presence of Many-Body Interactions
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.
