| Abstract: | The scaling behaviour of the fictitious time correlation length in stochastic quantization is investigated. Its implications in the numerical Langevin simulation are studied by the use of the two-dimensional 0(3) non-linear σ-model. It is discussed in connection with the measurement of the mass gap. Possible relations between the scaling behavior and higher order algorithms or the critical slowing down are also suggested. |
