P6_3-B30 is a three-dimensional boron crystal that functions as a spinless topological semimetal with a symmetry-enforced nodal surface on the kz=π plane and various Weyl fermions at high-symmetry points.
In disordered variants of the Su-Schrieffer-Heeger model, the entanglement entropy difference ΔS^A between half-filled and near-half-filled ground states is zero in the topological phase and finite in the trivial phase, providing a robust diagnostic that can outperform the topological invariant Q.
Interaction-induced doublons in a ring lattice with OAM map to effective SSH chains and Creutz ladders that support topologically protected edge states.
Hybridization of Machida-Shibata states under small on-site repulsion produces DIII topological superconductivity with Kramers Majorana pairs in chains and helical edge modes in 2D lattices.
In monitored SSH chains, spatially selective dissipation preserves edge-mode signatures in two-point correlations and disconnected entanglement entropy.
