On a stochastic model for the spin-down of solar type stars
Nicolas Leprovost, Eun-Jin Kim
Modeling the rotation history of solar-type stars is still an unsolved problem in modern astrophysics. One of the main challenges is to explain the dispersion in the distribution o…
Statistical theory of intermittency in a multi-scale model of MHD and micro-turbulence
Johan Anderson, Eun-jin Kim
Traditionally the effects of MHD instabilities and micro-instabilities on plasma confinement are investigated separately. However, these two instabilities often occur simultaneousl…
Predicting PDF tails of flux in plasma sheath region
Johan Anderson, Eun-jin Kim
This letter provides the first prediction of the probability density function (PDF) of flux in plasma sheath sheath region in magnetic fusion devices which is characterized by…
Turbulent transport and dynamo in sheared MHD turbulence with a non-uniform magnetic field
Nicolas Leprovost, Eun-Jin Kim
We investigate three-dimensional magnetohydrodynamics turbulence in the presence of both a large-scale velocity and non-uniform magnetic field. By assuming a turbulence driven by a…
Dynamo efficiency with shear in helical turbulence
Nicolas Leprovost, Eun-Jin Kim
To elucidate the influence of shear flow on the generation of magnetic field (the dynamo effect), we study the kinematic limit where the magnetic field does not backreact on the ve…
Non-perturbative models of intermittency in edge turbulence
Johan Anderson, Eun-jin Kim
A theory of the probability distribution function (PDF) tails of the blob density in plasma edge turbulence is provided. A simplified model of the fast convective radial transport…
Analytical theory of the probability distribution function of structure formation
Johan Anderson, Eun-jin Kim
The probability distribution function (PDF) tails of the zonal flow structure formation and the PDF tails of momentum flux by incorporating effect of a shear flow in ion-temperatur…
The momentum flux probability distribution function for ion-temperature-gradient turbulence
Johan Anderson, Eun-jin Kim
There has been overwhelming evidence that coherent structures play a critical role in determining the overall transport in a variety of systems. We compute the probability distribu…
Non-perturbative statistical theory of intermittency in ITG drift wave turbulence with zonal flows
Johan Anderson, Eun-jin Kim
The probability distribution functions (PDFs) of momentum flux and zonal flow formation in ion-temperature-gradient (ITG) turbulence are investigated, including the effect of the s…
