Abstract
Random matrix theory is used to show that the proximity to a supercond uctor opens a gap in the excitation spectrum of an electron gas confin ed to a billiard with a chaotic classical dynamics. In contrast, a gap less spectrum is obtained for a non-chaotic rectangular billiard, and it is argued that this is generic for integrable systems.
