Nuclei interacting with electrons in dense plasmas acquire electronic bound states, modify continuum states, generate resonances and hopping electron states, and generate short-range ionic order. The mean ionization state (MIS), i.e, the mean charge Z of an average ion in such plasmas, is a valuable concept: Pseudopotentials, pair-distribution functions, equations of state, transport properties...

The LTE Saha–Boltzman plasma ionization balance model and the Braginskii plasma electric resistance model are compared with the results by the suit of codes based on the average atom model, which is a quantum-mechanical version of the Temperature Dependent Thomas–Fermi Theory. The analysis is focused on low-Z Al, mid-Z Cu and higher-Z Mo plasmas in a broad ranges of electron temperature Te and ...

The relaxation of nonideal two-temperature plasmas is investigated with a kinetic approach. First the energy transfer between the electrons and ions is described using different approximations: the energy transfer through classical collisions (Landau-Spitzer approach) is reviewed; quantum diffraction and strong collisions are included by applying the quantum Boltzmann equation; the influence of...

In this paper, firstly, in $E_1^3$, we defined normal Fermi-Walker derivative and applied for the adapted frame. Normal Fermi-Walker parallelism, normal non-rotating frame, and Darboux vector expressions of normal Fermi-Walker derivative by normal Fermi-Walker derivative are given for adapted frame. Being conditions of normal Fermi-Walker derivative and normal non-rotating frame are examined fo...

Fermi gases with magnetically tunable interactions provide a clean and controllable laboratory system for modeling interparticle interactions between fermions in nature. The s-wave scattering length, which is dominant a low temperature, is made to diverge by tuning near a collisional (Feshbach) resonance. In this regime, two-component Fermi gases are stable and strongly interacting, enabling te...

Propagation of the finite amplitude electromagnetic wave through partially spin-polarized degenerate plasmas leads to an instability. This instability happens due interaction with small-frequency longitudinal spin-electron-acoustic waves. The strongest growth in high-density Fermi momentum close mec, where me is mass electron and c speed light. increase increment spin polarization found.
