Quantum mechanics for classical transport equations
Christof Wetterich
Classical transport equations with probabilistic initial conditions can be viewed as quantum systems. In a discrete version they are probabilistic automata. The time-local probabil…

Quantum field theory for classical fields
Christof Wetterich
For classical field theories with probabilistic initial conditions the classical field observables are an idealization. Their arbitrarily precise values poorly reflect the characte…

Complex wave functions, CPT and quantum field theory for classical generalized Ising models
Christof Wetterich
The quantum or quantum field theory concept of a complex wave function is useful for understanding the information transport in classical statistical generalized Ising models. We r…
