Andreev bound states for superconducting-ferromagnetic box
arXiv:cond-mat/0306523 · doi:10.1103/PhysRevB.69.092506
Abstract
Within the microscopic Bogoliubov--de Gennes (BdG) formalism an exact quantization condition for Andreev bound states of the ferromagnetic-superconducting hybrid systems of box geometry is derived and a semi-classical formula for the density of states is obtained. The semi-classical formula is shown to agree with the exact result, even when the exchange field , is much larger than the superconductor order parameter, provided is small compared with the Fermi energy.
