1D RELATIVISTIC UNCONFINED COULOMB PROBLEM FOR DIRAC EQUATION (Z < 137)

Abstract

Single-particle 1D Dirac matrix Hamiltonian can be expressed by the following equation,

where,  - Fermi velocity;

For carbon nanotubes or graphene nanoribbons: ;

 - band gap;

 - momentum operator acts along the axis of the effectively 1D system.
