In recent decades, great progress has been made in our understanding of zonal jets across
many subjects-atmospheric science, oceanography, planetary science, geophysical fluid …

In the context of toroidal gyrokinetic simulations, it is shown that a hierarchy of damped
modes is excited in the nonlinear turbulent state. These modes exist at the same spatial …

Nonlinear excitation of linearly stable microtearing modes—with zonal modes acting as a
catalyst—is shown to be responsible for the near-ubiquitous magnetic stochasticity and …

In gyrokinetic simulations, thousands of degrees of freedom are available to contribute to the
fluctuation spectrum. For wavevectors with a single linear instability, the unstable …

This work investigates the behavior of impurities in edge plasma of tokamaks using high-
resolution numerical simulations based on Hasegawa–Wakatani equations. Specifically, it …

This paper investigates non-intrusive Scientific Machine Learning (SciML) Reduced-Order
Models (ROMs) for plasma turbulence simulations. In particular, we focus on Operator …

Nonlinear dynamics in the two-dimensional multi-component plasma turbulence described
by the Hasegawa–Wakatani equation is investigated by using a data-driven modal analysis …

A notable feature of plasma turbulence is its propensity to retain features of the underlying
linear eigenmodes in a strongly turbulent state—a property that can be exploited to predict …

Transitionally turbulent flows frequently exhibit spatiotemporal intermittency, reflecting a
complex interplay between driving forces, dissipation, and transport present in these …

This paper focuses on the construction of non-intrusive Scientific Machine Learning (SciML)
Reduced-Order Models (ROMs) for nonlinear, chaotic plasma turbulence simulations. In …
