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 simulati…
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…
Hybrid simulation of Alfvén wave parametric decay instability in a laboratory relevant plasma
Feiyu Li, Xiangrong Fu, Seth Dorfman
Large-amplitude Alfvén waves are subject to parametric decays which can have important consequences in space, astrophysical, and fusion plasmas. Though the Alfvén wave parametric d…
Vacuum laser acceleration of super-ponderomotive electrons using relativistic transparency injection

Intense lasers can accelerate electrons to very high energy over a short distance. Such compact accelerators have several potential applications including fast ignition, high energ…
CoSyR: a novel beam dynamics code for the modeling of synchrotron radiation effects
C. -K. Huang, F. -Y. Li, H. N. Rakotoarivelo +7
The self-consistent nonlinear dynamics of a relativistic charged particle beam interacting with its complete self-fields is a fundamental problem underpinning many of the accelerat…
Parametric decay of Alfvénic wave packets in nonperiodic low-beta plasmas
Feiyu Li, Xiangrong Fu, Seth Dorfman
The parametric decay of finite-size Alfvén waves in nonperiodic low-beta plasmas is investigated using one-dimensional hybrid simulations. Compared with the usual small periodic sy…
Laser structured micro-targets generate MeV electron temperature at W/cm
Angana Mondal, Ratul Sabui, Sheroy Tata +14
Relativistic temperature electrons higher than 0.5 MeV are generated typically with laser intensities of about 10 W/cm. Their generation with high repetition rate lase…
Particle resonances and trapping of direct laser acceleration in a laser-plasma channel
F. -Y. Li, P. K. Singh, S. Palaniyappan +1
As one of the leading acceleration mechanisms in laser-driven underdense plasmas, direct laser acceleration (DLA) is capable of producing high-energy-density electron beams in a pl…
