Topological many-body scar states in dimensions one, two, and three


Ok, Seulgi; Choo, Kenny; Mudry, Christopher; Castelnovo, Claudio; Chamon, Claudio; Neupert, Titus (2019). Topological many-body scar states in dimensions one, two, and three. 033144 3, University of Zurich.

Abstract

We propose an exact construction for atypical excited states of a class of nonintegrable quantum many-body Hamiltonians in one, two, and three dimensions that display area-law entanglement entropy. These examples of many-body “scar” states have, by design, other properties, such as topological degeneracies, usually associated with the gapped ground states of symmetry-protected topological phases or topologically ordered phases of matter.
