DESCRIPTION:Abstract: Understanding the complex transport of particles in t
 urbulent plasmas is of great relevance in various fields. In astrophysics\
 , the diffusive transport of high-energy particles is often described in a
 n ensemble-averaged way\, employing a transport equation that describes th
 e time evolution of the particles distribution function in space and momen
 tum. The standard transport equation can also be re-written into a set of 
 stochastic differential equation. This allows for a Monte-Carlo approach o
 f solving for the particles distribution function\, which has been success
 fully applied to particle transport in the heliosphere\, diffusive shock a
 cceleration and recently to shear acceleration. Furthermore\, the stochast
 ic model allows for an extension to Levy flights\, modeling non-Gaussian d
 iffusion. Particle transport with such underlying power-law jump length di
 stributions cannot be represented by a normal transport equation\, but by 
 those including fractional derivatives. While solving fractional different
 ial equations is difficult\, stochastic models provide an elegant way to s
 olve for the particles distribution function.In this talk\, I will discuss
  the connection between Fokker-Planck equations and stochastic differentia
 l equations\, show applications to particle transport and acceleration and
  give a brief outlook to Levy flights.\nVortragende(r): Dr. Sophie Aerdker
