Secondary drift-driven instabilities in the presence of a parallel-propagating electromagnetic ion cyclotron wave and cold multi-component ions
Opal Issan, Patrick Kilian, Vadim Roytershteyn +2
Electromagnetic ion cyclotron (EMIC) waves are commonly observed in Earth's inner magnetosphere, particularly during geomagnetic storms driven by anisotropic ring-current protons.…

Understanding cold electron impact on parallel-propagating whistler chorus waves via moment-based quasilinear theory
Opal Issan, Vadim Roytershteyn, Gian Luca Delzanno +1
Earth's magnetosphere hosts a wide range of collisionless particle populations that interact through various wave-particle processes. Among these, cold electrons, with energies bel…

Improved algorithm for a two-dimensional Darwin particle-in-cell code
Dmytro Sydorenko, Igor D. Kaganovich, Alexander V. Khrabrov +3
A two-dimensional particle-in-cell code for simulation of low-frequency electromagnetic processes in laboratory plasmas has been developed. The code uses the Darwin method omitting…
