  2. Phase Space Representation Liouville propagation: Classical propagation Wigner function: Quantum propagation S. Habib, K. Shizume, W. H. Zurek Phys.Rev.Lett. 80 (1998) 4361-4365

  3. Separation time Z. P. Karkuszewski, J. Zakrzewski, W. H. Zurek Phys. Rev. A 65, 042113 (2002)

  4. Decoherence due to coupling to environment: effect on separation time?

  5. Characteristic function Momenta: Semiclassical analysis: Markovian Quantum Open System: Hamilton Jacobi:
