Query: Quantized invariant tori in Andreev billiards of mixed phase space   Comparing the results of exact quantum calculations and those obtained from
the EBK-like quantization scheme of Silvestrov et al [Phys. Rev. Lett. 90,
116801 (2003)] we show that the spectrum of Andreev billiards of mixed phase
space can basically be decomposed into a regular and an irregular part,
similarly to normal billiards. We provide the first numerical confirmation of
the validity of this quantization scheme for individual eigenstates and discuss
its accuracy.
