A many-body winding invariant based on Pancharatnam phases uniquely determines the 4^ν entanglement-spectrum degeneracy scaling in interacting generalized SSH chains, establishing symmetry-protected bulk-boundary correspondence.
In a dimerized staggered Hubbard ring at half filling, the many-body Wilson loop satisfies the exact identity W(-δ) = W(δ)* even in regimes where the Berry phase is unquantized and varies continuously.
Derives corrected orbital magnetic moment matrix elements for non-degenerate Bloch states including Berry connection contributions and shows reduced orbital Hall conductivity in bilayer TMDC and graphene systems.
Cavity-mediated interactions in an effective SSH Hamiltonian produce consistent topological phase diagrams across three markers, confirming edge states via correlations.
A review summarizing theoretical and experimental progress on disorder-induced topological phases including TAIs, quasiperiodic extensions, non-Hermitian systems, and many-body realizations.
