The shear Alfvén continuum of quasisymmetric stellarators
Elizabeth J. Paul, Abdullah Hyder, Eduardo Rodríguez +2
The shear Alfvén wave (SAW) continuum plays a critical role in the stability of energetic particle-driven Alfvén eigenmodes. We develop a theoretical framework to analyze the SAW c…

Ray-tracing laser-deposition model for plasma particle-in-cell simulation
Abdullah Hyder, Will Fox, Kirill Lezhnin +1
We develop a ray-tracing model for laser-plasma interaction suitable for coupling in-line into kinetic particle-in-cell plasma simulation. The model is based on inverse Bremsstrahl…

Particle-in-cell simulations of expanding high energy density plasmas with laser ray tracing
K. V. Lezhnin, S. R. Totorica, A. S. Hyder +5
The design and analysis of high energy density (HED) laser experiments typically rely on radiation hydrodynamics simulations. However, some laser-plasma interaction regimes are not…
