Query: Relation between Vortex core charge and Vortex Bound States   Spatially inhomogeneous electron distribution around a single vortex is
discussed on the basis of the Bogoliubov-de Gennes theory. The spatial
structure and temperature dependence of the electron density around the vortex
are presented. A relation between the vortex core charge and the vortex bound
states (or the Caroli-de Gennes-Matricon states) is pointed out. Using the
scanning tunneling microscope, information on the vortex core charge can be
extracted through this relation.
