TLDR
In this article, the properties of dense plasmas characteristic of the atmospheres of neutron stars and of the interior of massive white dwarfs are examined, and the problem of pressure ionization of hydrogen in a strong magnetic field and the crystallization of the quantum one-component plasma at finite temperature is discussed.Abstract:
We briefly examine the properties of dense plasmas characteristic of the atmospheres of neutron stars and of the interior of massive white dwarfs. These astrophysical bodies are natural laboratories for studying respectively the problem of pressure ionization of hydrogen in a strong magnetic field and the crystallization of the quantum one-component plasma at finite temperature.read more

Nonlinear aspects of quantum plasma physics
Padma Kant Shukla,Bengt Eliasson +1 more
TL;DR: In this paper, the authors present theoretical backgrounds for some important nonlinear aspects of wave-wave and wave-electron interactions in dense quantum plasmas, focusing on nonlinear electrostatic electron and ion plasma waves, novel aspects of three-dimensional quantum electron fluid turbulence, as well as nonlinearly coupled intense electromagnetic waves and localized plasma wave structures.

A magnetohydrodynamic model for quantum plasmas
TL;DR: In this paper, the quantum hydrodynamic model for charged particle systems is extended to the cases of nonzero magnetic fields, and conditions for equilibrium in ideal quantum magnetohydrodynamics are established.

Linear and nonlinear ion-acoustic waves in an unmagnetized electron-positron-ion quantum plasma
TL;DR: In this paper, the linear and nonlinear properties of the ion-acoustic waves (IAWs) were investigated by using the quantum hydrodynamic equations together with the Poisson equation in a three-component quantum electron-positron-ion plasma.

Thermodynamic Functions of Dense Plasmas: Analytic Approximations for Astrophysical Applications
TL;DR: In this article, the authors present analytic approximations of thermodynamic functions of fully ionized nonideal electron-ion plasmas, applicable in a wide range of plasma parameters, including the domains of non-degenerate and degenerate, nonrelativistic and relativistic electrons, weakly and strongly coupled Coulomb liquids, classicaland quantum Coulomb crystals.

Ground state of the electron gas by a stochastic method
David M. Ceperley,Berni J. Alder +1 more
TL;DR: An exact stochastic simulation of the Schroedinger equation for charged Bosons and Fermions was used to calculate the correlation energies, to locate the transitions to their respective crystal phases at zero temperature within 10%, and to establish the stability at intermediate densities of a ferromagnetic fluid of electrons.

Path integrals in the theory of condensed helium
TL;DR: In this paper, the authors introduce a picture of a boson superfluid and show how superfluidity and Bose condensation manifest themselves, showing the excellent agreement between simulations and experimental measurements on liquid and solid helium for such quantities as pair correlations, the superfluid density, the energy, and the momentum distribution.
