1201.6212 (C. Wetterich)

Quantum fermions and quantum field theory from classical statistics    [PDF]

C. Wetterich
An Ising-type classical statistical ensemble can describe the quantum physics
of fermions if one chooses a particular law for the time evolution of the
probability distribution. It accounts for the time evolution of a quantum field
theory for Dirac particles in an external electromagnetic field. This yields in
the non-relativistic one-particle limit the Schr\"odinger equation for a
quantum particle in a potential. Interference or tunneling arise from classical
probabilities.
