Nonlinear velocity redistribution caused by energetic-particle-driven geodesic acoustic modes, mapped with the beam-plasma system
A. Biancalani, N. Carlevaro, A. Bottino +2
The nonlinear dynamics of energetic particle (EP) driven geodesic acoustic modes (EGAM) in tokamaks is investigated, and compared with the beam-plasma system (BPS). The EGAM is stu…
Resonance overlap and non-linear velocity spread in Hamiltonian beam-plasma systems
Nakia Carlevaro, Giovanni Montani, Fulvio Zonca
We analyze some specific features of the beam-plasma instability. In particular, non-perturbative effects in the dispersion relation are studied when the standard perturbative inve…
Behavior of thin disk crystalline morphology in the presence of corrections to ideal magnetohydrodynamics
Giovanni Montani, Mariachiara Rizzo, Nakia Carlevaro
We analyze an axisymmetric magnetohydrodynamics configuration, describing the morphology of a purely differentially rotating thin plasma disk, in which linear and non-linear pertur…
Coexistence of Magneto-Rotational and Jeans Instabilities in an Axisymmetric Nebula
Giovanni Montani, Giovanni Palermo, Nakia Carlevaro
We analyze the magneto-rotational instability (MRI) effects on gravitational collapse and its influence on the instability critical scale. In particular, we study an axisymmetric n…
Study of MRI in stratified viscous plasma configuration
Nakia Carlevaro, Giovanni Montani, Fabrizio Renzi
We analyze the morphology of the Magneto-rotational Instability (MRI) for a stratified viscous plasma disk configuration in differential rotation, taking into account the so-called…
On the viability of the single wave model for the beam plasma instability
Nakia Carlevaro, Giovanni Montani, Davide Terzani
We analyze the interaction of a cold fast electron beam with a thermalized plasma, in the presence of many Langmuir modes. The work aims at characterizing the deviation of the syst…
