Particle-in-Cell Simulation of the Parametric Decay Instability of Alfvén Waves with Absorbing Boundary Conditions
Vijay Shankar, Feiyu Li, Seth Dorfman +1
The Alfvén wave parametric decay instability (PDI) facilitates energy transfer, plasma heating, and turbulence generation in space, astrophysical, and fusion plasmas. Most simulat…

A novel scheme for measuring the growth of Alfven wave parametric decay instability using counter-propagating waves
Feiyu Li, Seth Dorfman, Xiangrong Fu
The parametric decay instability (PDI) of Alfven waves -- where a pump Alfven wave decays into a backward-propagating child Alfven wave and a forward ion acoustic wave -- is a fund…

Effects of wave damping and finite perpendicular scale on three-dimensional Alfven wave parametric decay in low-beta plasmas
Feiyu Li, Xiangrong Fu, Seth Dorfman
Shear Alfven wave parametric decay instability (PDI) provides a potential path toward significant wave dissipation and plasma heating. However, fundamental questions regarding how…
