Interactions in the generalized SSH model produce interacting SPT phases, a sublattice-density-breaking phase, CDW phases, Luttinger liquids, and a gapless SPT phase with protected edge states.
Derives exact bulk-boundary correspondence allowing extraction of edge-mode degeneracy from bulk entanglement spectrum in critical free-fermion systems of arbitrary dimensions.
The work constructs an equivalence class of 3D lattice models realizing single Weyl fermions through symmetry-protected topological states and controlled symmetry breaking, linking them to gapless phases in superconductors and superfluids.
Staggered fermion actions meet the criteria for symmetric mass generation in lattice QCD, with Goldstone tetraquark states as a signature of the type-II phase.
