摘要：

We have studied the interplay of Andreev reflection and cyclotron motion of quasiparticles at a superconductor- normal-metal interface with a strong magnetic field applied parallel to the interface. Bound states are formed due to the confinement introduced by both the external magnetic field and the superconducting gap. These bound states are a coherent superposition of electron and hole edge excitations similar to those realized in finite quantum-Hall samples. Vie find the energy spectrum for these Andreev edge states and calculate transport properties.
