Query: Effect of strong intersite Coulomb interaction on the topological
  properties of a superconducting nanowire   For superconducting nanowire with the pairing of extended s-type symmetry,
Rashba spin-orbit interaction in a magnetic field, the influence of strong
intersite charge correlations on single-particle Majorana excitations is
analyzed. This problem is investigated on the basis of the density matrix
renormalization group numerical method. It is shown that with an increase in
the repulsion intensity of electrons located at the neighboring sites, two
subbands emerge in the lower Hubbard band of the open system. Based on
calculations of the Majorana polarization and degeneracy of the entanglement
spectrum, it was found that a topologically nontrivial phase with one edge
state survives at the edge of each of the subbands where the concentration of
electrons or holes is minimal.
