Ion temperature gradient mode mitigation by energetic particles, mediated by forced-driven zonal flows
Juvert Njeck Sama, Alessandro Biancalani, Alberto Bottino +14
In this work, we use the global electromagnetic and electrostatic gyro kinetic approaches to investigate the effects of zonal flows forced-driven by Alfvén modes due to their excit…
Nonlinear interaction of Alfvénic instabilities and turbulence via the modification of the equilibrium profiles
A. Biancalani, A. Bottino, D. Del Sarto +10
Nonlinear simulations of Alfvén modes (AM) driven by energetic particles (EP) in the presence of turbulence are performed with the gyrokinetic particle-in-cell code ORB5. The AMs c…
Effect of temperature anisotropy on the dynamics of geodesic acoustic modes
J. N. Sama, A. Biancalani, A. Bottino +7
In this work, we revisit the linear gyro-kinetic theory of geodesic acoustic modes (GAMs) and derive a general dispersion relation for an arbitrary equilibrium distribution functio…
Anisotropic electron heating in turbulence-driven magnetic reconnection in the near-Sun solar wind
Luca Franci, Emanuele Papini, Alfredo Micera +5
We perform a high-resolution two-dimensional fully-kinetic numerical simulation of a turbulent plasma system with observation-driven conditions, in order to investigate the interpl…
Onset of fast "ideal" tearing in thin current sheets: dependence on the equilibrium current profile
Fulvia Pucci, Marco Velli, Anna Tenerani +1
In this paper we study the scaling relations for the triggering of the fast, or "ideal", tearing instability starting from equilibrium configurations relevant to astrophysical as w…
Saturation of energetic-particle-driven geodesic acoustic modes due to wave-particle nonlinearity
A. Biancalani, I. Chavdarovski, Z. Qiu +6
The nonlinear dynamics of energetic-particle (EP) driven geodesic acoustic modes (EGAM) is investigated here. A numerical analysis with the global gyrokinetic particle-in-cell code…
