Abstract

We investigate quasiparticle states associated with an isolated vortex in a d-wave superconductor using a self-consistent Bogoliubov--de Gennes formalism. For a pure d_x²\ensuremath-y² superconductor we find that there exist no bound states in the core; all the states are extended with continuous energy spectrum. This result is inconsistent with the existing experimental data on cuprates. We propose an explanation for this data in terms of a magnetic-field-induced d_x²\ensuremath-y²+id_xy state recently invoked in connection with the thermal conductivity measurements on Bi₂Sr₂CaCu₂O₈.
