Study of Regular and Irregular States in Generic Systems
  In this work we semiclassically analyzed the high lying eigenstates of a mixed type Hamiltonian system. For the regular states we employ the Einstein-Brillouin-Keller quantization, while for the chaotic states, following the principle of uniform semiclassical condensation, we obtain a prediction for their wavefunction autocorrelation function.
