摘要：

A new type of classical billiard-the Andreev billiard-is investigated using the tangent map technique. Andreev billiards consist of a normal region surrounded by a superconducting region. In contrast with previously studied billiards, Andreev billiards are integrable in zero magnetic field, regardless of their shape. A magnetic field renders chaotic motion in a generically shaped billiard, which is demonstrated for the Bunimovich stadium by examination of both Poincare sections and Lyapunov exponents. The issue of the feasibility of certain experimental realizations is addressed.
