A new method of quantization of classical solutions
D. V. Antonov · Journal of Experimental and Theoretical Physics Letters · 1996
The stochastic quantization method of Parisi and Wu is used to derive exact equations for the correlators of quantum fluctuations around the classical solution in the massless φ 4 theory. The equations obtained are then solved in the lowest orders of perturbation theory, and the first correction to the free propagator of a quantum fluctuation is calculated.
