Energetic particles, Shafranov shift and finite effects on TAE, KBM and ITG instabilities in global electromagnetic gyrokinetic simulations
B. Rofman, G. Di Giannatale, A. Mishchenko +8
Burning plasma is computationally challenging to simulate due to the multi-scale interactions between energetic particles (EPs), Alfven eigenmodes, and microinstabilities that driv…

Role of Shafranov shift, zonal structures on the behavior of TAEs, AAEs and microinstabilities in the presence of energetic particles
B. Rofman, G. Di Giannatale, A. Mishchenko +8
In future nuclear fusion reactors, even a small fraction of fusion-born energetic particles (EP) about 100 times hotter than the thermal bulk species, contributes substantially to…

Modulational instability of Geodesic-Acoustic-Mode packets
David Korger, Emanuele Poli, Alessandro Biancalani +3
Isolated, undamped geodesic-acoustic-mode (GAM) packets have been demonstrated to obey a (focusing) nonlinear Schrödinger equation (NLSE) [E. Poli, Phys. Plasmas 2021]. This equati…
