Quantum fermions from classical statistics

Institut für Theoretische Physik
Univ. Heidelberg

Quantum mechanics can be obtained from classical statistics. It arises if the time evolution of the probability distribution follows an appropriate law , and if correlation functions appropriate for suitable subsystems are used for a description of measurements. As an example , we formulate the evolution law for the classical probability distribution that describes a quantum field theory for relativistic fermions. The one - particle states obey the usual rules of quantum mechanics , with interference and uncertainty relation. We also introduce the concept of a classical wave function for the description of classical statistics.
