The frictional force (stopping power) acting on a test electron moving through an ideal electron gas is calculated by taking into account electron-neutral atom collisions using the linear plasma response formalism. This allows us to elucidate how the effective Coulomb logarithm is affected by electron-neutral collisions. In agreement with a recent investigation by Hagelaar, Donko, and Dyatko [Phys. Rev. Lett. 123, 025004 (2019)PRLTAO0031-900710.1103/PhysRevLett.123.025004], we observe that the…

Particle-in-cell Monte Carlo-collision modeling of non-ideal effects in wave-heated dense microplasmas

A computational model for non-ideal plasma effects during the time evolution of a second-stage laser-heated discharge at high pressures is presented. The model extends a classical one-dimensional

Diffusion regime of electron–electron collisions in weakly ionized plasmas

We consider weakly ionized plasma where frequent elastic scattering of electrons on neutrals change the individual acts and the rate of electron-electron collisions significantly. In this case, the

Ion drag force in dusty plasmas

A short review of different approaches to calculating the ion drag force is presented. First, a concise summary of the previously published results of the pair collision approach is given. Then, the

Passage of Charged Particles through Plasma

The plasma has been treated phenomenologically as a homogeneous dispersive medium characterized by a "dielectric constant" which is a function not only of the frequency of the applied field (as in


The nature of the effective interaction between particles when correlation effects are taken into account is discussed. It has been observed that the encounters between the particles are not binary,

Hybrid approach to the ion drag force

A detailed calculation of the ion drag force acting on a single grain in a collisionless Maxwellian plasma with an arbitrary velocity of the ion flow is carried out. The traditional binary collision

Ion drag force on an absorbing body in highly collisional plasmas

The force acting on a small absorbing body embedded in a highly collisional plasma with drifting ions is calculated using the linear response formalism. It is shown that the absorption introduces

Modification of the Coulomb Logarithm due to Electron-Neutral Collisions.

We demonstrate that in partially ionized plasmas, Coulomb scattering can be significantly perturbed by electron collisions with neutral gas particles, and that this effect can be incorporated in the

Kinetic approach for the ion drag force in a collisional plasma.

The linear kinetic approach to calculate the ion drag force in a collisional plasma is generalized and the importance of the self-consistent kinetic consideration is highlighted.

Energy loss of heavy ions in dense plasma. I. Linear and nonlinear Vlasov theory for the stopping power.

An improved {ital dE/{ital dx} formula for plasma is derived in closed form and readily applicable for stopping-power calculations; it is identical to the standard result for {ital v}{sub {ital p}}, but also describes the limit of the limit correctly.
