recommendations! Published in 2019 at "Physics of Plasmas"

DOI: 10.1063/1.5083176

Abstract: In confined plasmas, a localized fluctuation in a marginal or weakly damped region will propagate and generate an avalanche if it exceeds a threshold. In this letter, a new model for turbulence spreading based on… read more here.

DOI: 10.1088/1741-4326/ad2ca9

Abstract: Turbulence spreading from the edge to the core region of a tokamak with a resonant magnetic perturbation (RMP) is investigated using an electromagnetic Landau-fluid model in a toroidal geometry. As a RMP field with an… read more here.

recommendations! Published in 2025 at "Physical review. E"

DOI: 10.1103/cmf5-sf8x

Abstract: This paper presents a simple model for such processes as chaos spreading or turbulence spillover into stable regions. In this simple model the essential transport occurs via inelastic resonant interactions of waves on a lattice.… read more here.

DOI: 10.1103/physrevlett.128.125001

Abstract: Turbulence spreading into the edge stochastic magnetic layer induced by magnetic fluctuation is observed at the sharp boundary region in the large helical device. The density fluctuation excited at the sharp boundary region with a… read more here.

DOI: 10.3938/jkps.73.747

Abstract: This paper presents a pedagogical review of the physics of mesoscopic transport events and their role in the breakdown of Fick’s Law for turbulent transport in magnetically confined plasma. It is now clear that the… read more here.
