Elastic and breaking properties of epitaxial face‐centered crystals in neutron star crusts and white dwarf cores Contrib. Plasm. Phys. (IF 1.6) Pub Date : 2024-03-13 D. A. Baiko
Crystallization of dense matter in neutron star crusts and white dwarf cores may be similar to epitaxial crystal growth in terrestrial laboratories. However, in stellar crystals, the spacing between horizontal planes has to gradually increase with the outward movement of the crystallization front, tracing decrease of the electron density. This process produces Coulomb crystals with stretched rather

The self-organization of a magnetized multi-ion plasma, composed of inertialess electrons and inertial H+, He+, and O+ ions, leads to the formation of quadruple Beltrami (QB) field structures. The QB self-organized state is a linear combination of four single Beltrami fields, and it is a non-force-free state that shows strong magnetofluid coupling. Moreover, the QB state is characterized by four relaxed

An optimized divertor design is crucial to maximize the lifetime of plasma-facing components and reduce costs of future fusion power plants. Numerical shape optimization could be a powerful tool to obtain improved designs in an automated way. However, it is not trivial to apply due to the need of a field-aligned and boundary-fitted grid for simulating the plasma and quantifying the heat load. This

The processes in far scrape-off layer (SOL) and the plasma interaction with the first-wall (FW) elements may notably affect the tokamak discharge, since they define fuel and impurity recycling, material erosion and redeposition, wall surface heating, etc. For a long time, the far SOL description in most plasma edge transport codes was insufficient or absent at all, and so particle and heat fluxes onto

Only recently, plasma edge simulations up to the wall have been enabled with SOLPS-ITER. This requires dedicated gridding techniques to reconcile grid alignment with the magnetic field and refinement toward the wall as grid quality is primordial to ensure fast and reliable convergence. Therefore, the gridding approach for the grids up to the wall is analyzed and improved. A truncation error analysis

The burst of edge-localized modes (ELMs) leads to an increase in the energy and particle fluxes to the divertor target. Tungsten (W) is chosen as the primary candidate material for plasma-facing components (PFCs) in the future fusion devices, and EAST has already upgraded all divertors to use W. Therefore, understanding tungsten target erosion during ELMs and finding the correlation between erosion

A linear plasma device (LPD) module has been developed under the BOUT++ framework to simulate plasma transport in the MPS-LD. However, previously, the LPD module used a simplistic neutral particle model that only includes particle density and velocity, which prevents the full understanding of the plasma-neutrals interactions. In this work, we further optimize the neutral model by using a more complete

Quite a many electron transport problems in condensed matter physics are analyzed with a quasiparticle Boltzmann equation.

Hybrid simulation of the plasma characteristics in a dual-frequency dual-antenna inductively coupled plasma discharge Contrib. Plasm. Phys. (IF 1.6) Pub Date : 2023-10-12 Xiao-Yan Sun, Ming-Hui Yang, Wei-Li Shao, Xin Tao, Long-Wei Li
Dual-frequency (DF) dual-antenna inductively coupled plasma (ICP) sources have been proposed as one of the methods to produce large-area uniform plasma. In this study, a hybrid model, consisting of a fluid module and an electron Monte Carlo (eMC) module, is used to further investigate the modulation of the plasma characteristics (i.e., induced electric field, electron energy distribution, electron

The effect of magnetic field on the electric breakdown trajectory of high-voltage electric pulse rock breaking Contrib. Plasm. Phys. (IF 1.6) Pub Date : 2023-10-02 Weiji Liu, Xin Zhou, Xiaohua Zhu
High-voltage electric pulse drilling technology has the advantages of high rock-breaking efficiency, low energy consumption for rock breaking, and good quality of well wall, which is a new and efficient potential rock-breaking method. In this paper, we constructed a numerical simulation model of rock electric breakdown and realized the whole process of rock breaking and plasma channel generation by

Effect of elastic scattering between ions and neutral particles on ion transport perpendicular to magnetic fields in divertor plasmas Contrib. Plasm. Phys. (IF 1.6) Pub Date : 2023-09-18 Daisuke Umezaki, Hideaki Matsuura, Kazuo Hoshino
In divertor plasmas, atomic processes play a significant role in reducing the divertor heat load. In particular, the elastic scattering between ions and neutral particles can be characterized as a large-angle scattering; this is in contrast with Coulomb scattering, which is dominated by small-angle scattering. In a large-angle scattering, a large fraction of the ion energy is transferred to the neutral

Coulomb effects in electronic transport Contrib. Plasm. Phys. (IF 1.6) Pub Date : 2023-09-17 Boris N. Narozhny
Charge transport in metals and semiconductors is often dominated by electron-impurity and electron–phonon scattering. Coulomb effects could be found in small corrections to the leading behavior, drag effects in specially fabricated samples, compensated semimetals, and hydrodynamic phenomena in ultra-pure materials. In contrast, electrical resistivity in strongly correlated systems is poorly understood

Plasmonic effects in the neutralization of slow ions at a metallic surface Contrib. Plasm. Phys. (IF 1.6) Pub Date : 2023-09-16 Marnik Bercx, Selma Mayda, Diederik Depla, Bart Partoens, Dirk Lamoen
Secondary electron emission is an important process that plays a significant role in several plasma-related applications. As measuring the secondary electron yield experimentally is very challenging, quantitative modelling of this process to obtain reliable yield data is critical as input for higher-scale simulations. Here, we build upon our previous work combining density functional theory calculations

Magnetized dusty plasma: On issues of its complexity and magnetization of charged dust particles Contrib. Plasm. Phys. (IF 1.6) Pub Date : 2023-09-15 Mangilal Choudhary
It is possible to excite various linear and nonlinear low-frequency modes in dusty plasma, which is an admixture of electrons, ions, gas atoms, and negatively charged solid particles. The experimental as well as theoretical study of these low-frequency dynamical modes in dusty plasma is very complex because of the involvement of dynamics of electrons, ions, and neutrals. If the external magnetic field

Influence of plasma inhomogeneity and ohmic heating on the nonlinear absorption of intense laser pulse in collisional magnetized plasma Contrib. Plasm. Phys. (IF 1.6) Pub Date : 2023-09-07 R. Fallah, R. Khooniki, S. M. Khorashadizadeh, A. R. Niknam
The nonlinear absorption in the interaction of an intense laser pulse with a collisional magnetized plasma is studied by considering the effects of plasma inhomogeneity, ohmic heating, and ponderomotive force. For this purpose, we obtain the plasma electron density, the effective dielectric permittivity, and the wave equation using the Maxwell and hydrodynamic equations and solve this equation by the

Unusual dynamics and nonlinear thermal self-focusing of initially focused magnetoacoustic beams in a plasma Contrib. Plasm. Phys. (IF 1.6) Pub Date : 2023-09-04 Anna Perelomova
Unusual thermal self-focusing of two-dimensional beams in plasma which axis is parallel to the equilibrium straight magnetic field is considered. The equilibrium parameters of plasma determine scenario of a beam divergence (usual or unusual) which is stronger as compared with a flow without magnetic field. Nonlinear thermal self-action of a magnetosonic beam behaves differently in the ordinary and
