Absztrakt:
We present a detailed semiclassical study of a clean disk-shaped
insulator-normal-metal-superconductor hybrid system in a magnetic
field. It is based on an exact secular equation that we derived within
the microscopic Bogoliubov-de Gennes (BdG) formalism. Results obtained
from a classification of electron and hole orbits are in excellent
agreement with those from an exact numerical diagonalization of the BdG
equation. Our analysis opens up different possibilities for determining
thermodynamic properties of mesoscopic hybrid systems.
