  We consider states bound at the flip of the electric field in buckled
silicene. Along the electric flip lines a topological confinement is formed
with the orientation of the charge current and the resulting magnetic dipole
moment determined by the valley index. We compare the topological confinement
to the trivial one that is due to a local reduction of the vertical electric
field but without energy gap inversion. For the latter the valley does not
protect the orientation of the magnetic dipole moment from inversion by
external magnetic field. We demonstrate that the topologically confined states
can couple and form extended bonding or antibonding orbitals with the energy
splitting influenced by the geometry and the external magnetic field.
