This is a finite-size effect whose physical origin is directly associated with the equilibrium mass-current density. Our numerical findings for the ground state suggest a bulk-boundary correspondence between characteristic features of the edge-bound transverse polarization and the changes in the momentum-space topology of the bulk.PhysicsCondensed matterJournal Article1873-21356634642000033799
