Abstract: In this work we present the original Langevin's method to study the Brownian motion of a charged particle across a constant magnetic field. Langevin's strategy allows transforming the Langevin equation into a deterministic one associated… read more here.

Abstract: Continuous time random walks and Langevin equations are two classes of stochastic models for describing the dynamics of particles in the natural world. While some of the processes can be conveniently characterized by both of… read more here.

DOI: 10.1103/physrevd.95.054509
Abstract: Although the complex Langevin method can solve the sign problem in simulations of theories with complex actions, the method will yield the wrong results if known validity conditions are not satisfied. We present a novel… read more here.
