Query: Topological states and interplay between spin-orbit and Zeeman
  interactions in a spinful Su-Schrieffer-Heeger nanowire   The interplay between the spin-orbit and Zeeman interactions acting on a
spinful Su-Schrieffer-Heeger model is studied based on an InAs nanowire
subjected to a periodic gate potential along the axial direction. It is shown
that a nontrivial topological phase can be achieved by regulating the
confining-potential configuration. In the absence of the Zeeman field, we prove
that the topology of the chain is not affected by the Rashba spin-orbit
interaction due to the persisting chiral symmetry. The energies of the edge
modes can be manipulated by varying the magnitude and direction of the external
magnetic field. Remarkably, the joint effect of the two spin-related
interactions leads to novel edge states that appear in the gap formed by the
anti-crossing of the bands of a finite spinful dimerized chain, and can be
merged into the bulk states by tilting the magnetic-field direction.
