Stochastic quantization with colored noise

Studying the topological properties of the QCD vacuum, observables obtained from lattice simulations are suffering from short-distance fluctuations. To solve this problem, smoothening methods such as cooling and the Wilson flow have been developed. We present a method based on stochastic quantization with UV-regulated noise enabling a direct control of the quantum fluctuations at all lattice momentum scales. Smoothened configurations are generated from the beginning. The method is tested on a scalar field theory in two and four dimensions as well as pure SU(2) gauge theory. Effects of colored noise on observables are analyzed. Moreover, we investigate the existence of a scale above which physical quantities become independent of UV fluctuations at larger scales. We present and discuss our recent results.
