The ghost Gutzwiller variational embedding framework recovers an effective band structure for topological phases in strongly correlated systems and reveals topologically nontrivial Hubbard bands with edge states in the interacting Bernevig-Hughes-Zhang model.
Topological surface phonons in isostatic lattices with z=2d become finite-frequency surface phonons in superisostatic lattices with z>2d when next-nearest-neighbor springs or bending forces are added.
In an off-diagonal Aubry-André-Harper chain, transport signatures distinguish edge states, in-band bulk states, and band-edge bulk states by their system-size dependence, resonance broadening, and dephasing sensitivity.

Transport characteristics of bulk and edge states in an off-diagonal Aubry--Andr\'e--Harper chain
In an off-diagonal Aubry-André-Harper chain, transport signatures distinguish edge states, in-band bulk states, and band-edge bulk states by their system-size dependence, resonance broadening, and dephasing sensitivity.
