Master Fields, Drift and Dispersion in the Stochastic Limit of Quantum Theory

  • L. Accardi
  • F. G. Cubillo


This work is a detailed study of the convergence of the rescaled creation and annihilation densities, which lead to the master fields, and the form of the drift in the stochastic limit of quantum theory. The approach, based on the distributional theory of Fourier transforms, dispenses with the “analytical condition” and other restrictions usually considered and also establishes the dependence of the stochastic golden rules upon the dispersion function of the quantum field.
