Partition Functions and Mass Action Constants of Plasmas of Light Elements at Higher Temperatures

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT We first analyze the relations between the work of Planck and Klimontovich and show that Klimontovich's kinetic theory of non‐ideal plasmas confirms Planck's partition function for the hydrogen plasma. We discuss and check the Planck‐Brillouin‐Larkin (PBL) expressions for Hydrogen with PIMC calculations and derive new partition functions and ...

Non‐Markovian Quantum Kinetic Simulations of Uniform Dense Plasmas: Mitigating the Aliasing Problem

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Dense quantum plasmas out of equilibrium are successfully modeled using quantum kinetic equations, such as the quantum Boltzmann, Landau, or Balescu–Lenard equation. However, these equations do not properly take into account correlation effects, which require the use of generalized non‐Markovian kinetic equations.

Predicting the Uniform Electron Gas Stopping Power at Moderate and Strong Coupling

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT This paper presents a detailed study of the stopping power of a homogeneous electron gas in moderate and strong coupling regimes using the self‐consistent version of the method of moments as the key theoretical approach capable of expressing the dynamic characteristics of the system in terms of the static ones, which are the moments.

A review of multiscale numerical modeling of rock mechanics and rock engineering

open access: yesDeep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Synthesis, Characterization, Magnetic Properties, and DFT Investigations of Heterobimetallic Nickel–Lanthanide LNiIILnIII (Ln = Ce, Gd, Tb, Dy) Complexes Supported by Schiff Base Ligands

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Four 3d4f heterobimetallic Schiff base complexes are designed from the ditopic N,N’‐bis(3‐methoxysalicylaldiimine)‐1,3‐propylene‐2‐ol ligand. Experimental dc magnetic measurements and density functional theory computational investigations converge to antiferromagnetic exchange interaction between Ni(II) and Ce(III) ions while ferromagnetic interaction ...

Tree graph representation of hamiltonian paths

open access: yesComputers & Mathematics with Applications, 1994
AbstractPaths along faces of a polyhedron can be assimilated to paths along the branches of a tree graph. This paper shows the pruned trees corresponding to all Hamiltonian paths of regular polyhedra enumerated by the author in a previous paper [1].

Strain Effect on the Electronic, Optical, and Mechanical Properties of Inorganic Mg3NBr3 Perovskite: A DFT Study

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT This study investigates the potential of lead‐free Mg3NBr3 inorganic halide perovskites for photovoltaic and optoelectronic applications through comprehensive first‐principles density functional theory (FP‐DFT) calculations. This analysis reveals that Mg3NBr3 behaves as an indirect bandgap semiconductor with tunable electronic transitions in ...
