NON-DIFFUSIVE TRANSPORT IN NUMERICAL SIMULATIONS OF MAGNETICALLY-CONFINED TURBULENT PLASMAS

摘要

In this contribution, we discuss some recent advances in the application of diagnostics derived from both continuous-time random walks (CTRWs) and fractional differential equations (FDEs) to the characterization of non-diffusive transport features in numerical simulations of magnetically-confined turbulent plasmas in a variety of situations. An introduction to the main ideas and mathematics of CTRWs and FDEs is also provided.
