Exploring strong correlations in flat bands
One spectacular phenomenon in quantum many-body systems is the emergence of non-local quasiparticles with fractional quantum numbers and anyonic statistics. Of fundamental interest, fractionalization also holds promise for fault-tolerant quantum computation motivating the search for such exotic phases of matter. Signatures of this phenomenon remain sparse and mostly restricted to fractional quantum Hall states, despite being predicted to also occur in other systems such as frustrated quantum magnets. An essential feature shared by both systems is the massive ground state degeneracy, or flat band, out of which fractionalization emerges. The underlying non-local topological order of such…
