Observation of the Korteweg-de Vries soliton in molecular dynamics simulations of a dusty plasma medium
Sandeep Kumar, Sanat Kumar Tiwari, Amita Das
The excitation and evolution of Korteweg-de Vries (KdV) solitons in a dusty plasma medium are studied using Molecular Dynamics (MD) simulations. The dusty plasma medium is modelled…
Thermodynamic State Variables in Quasi-Equilibrium Ultracold Neutral Plasma
Sanat Kumar Tiwari, Nathaniel R. Shaffer, Scott D. Baalrud
The pressure and internal energy of an ultracold plasma in a state of quasi-equilibrium are evaluated using classical molecular dynamics simulations. Coulomb collapse is avoided by…
Effective Potential Theory for Diffusion in Binary Ionic Mixtures
Nathaniel R. Shaffer, Scott D. Baalrud, Jérôme Daligault
Self-diffusion and interdiffusion coefficients of binary ionic mixtures are evaluated using the Effective Potential Theory (EPT), and the predictions are compared with the results…
Influence of coupling on thermal forces and dynamic friction in plasmas with multiple ion species
Grigory Kagan, Scott D. Baalrud, Jerome Daligault
The recently proposed effective potential theory [Phys. Rev. Lett. 110, 235001 (2013)] is used to investigate the influence of coupling on inter-ion-species diffusion and momentum…
Particle-in-cell study of the ion-to-electron sheath transition
Brett Scheiner, Scott D. Baalrud, Matthew M. Hopkins +2
The form of a sheath near a small electrode, with bias changing from below to above the plasma potential is studied using 2D particle-in-cell (PIC) simulations. Five cases are stud…
