Electronic structure of vortices pinned by columnar defects in $p_x\pm i{p}_y$ superconductors

V. L. Vadimov, A. S. Mel'nikov

The electronic structure of a vortex pinned by an insulating columnar inclusion in a type-II chiral $p_x\pm i{p}_y$ superconductor is studied within the Bogolubov-de Gennes theory.…
