Fast and Accurate Numerical Integration of the Langevin Equation with Multiplicative Gaussian White Noise

Entropy
A univariate stochastic system driven by multiplicative Gaussian white noise is considered. The standard method for simulating its Langevin equation of motion involves incrementing the system’s state variable by a biased Gaussian random number at each ...

Energy deposition and deflection of α particles in hot dense plasmas relevant to inertial confinement fusions

Nuclear Fusion, 2023
Based on the kinetic theory, improved T -matrix models for the continuous-slowing-down and the linear-energy-transfer stopping powers are established at the same level, where multiple scattering effects and the related transverse deflection are accounted
