    "abstract": "A deterministic model with a large number of continuous and discrete degrees\nof freedom is described, and a statistical treatment is proposed. The model\nexactly obeys a Schrodinger equation, which has to be interpreted exactly\naccording to the Copenhagen prescriptions. After applying a Hartree-Fock\napproximation, the model appears to describe genuine quantum particles that\ncould be used as a starting point for field variables in a quantum field\ntheory. In the deterministic model it is essential that information loss\noccurs, but the corresponding quantum system is unitary and exactly preserves\ninformation.
