Uniform Semiclassical Wavepacket Propagation and Eigenstate Extraction   in a Smooth Chaotic System
  A uniform semiclassical propagator is used to time evolve a wavepacket in a smooth Hamiltonian system at energies for which the underlying classical motion is chaotic. The propagated wavepacket is Fourier transformed to yield a scarred eigenstate.
