We discuss the complete theory of spin-1/2 electron-positron quantum plasmas, when electrons and positrons move with velocities mach smaller than the speed of light. We derive a set of two fluid quantum hydrodynamic equations consisting of the continuity, Euler, spin (magnetic moment) evolution equations for each species. We explicitly include the Coulomb, spin-spin, Darwin and annihilation interactions. The annihilation interaction is the main topic of the paper. We consider the contribution… 

A transverse separate-spin-evolution streaming instability and new wave solutions in electron–positron–ion plasmas

This paper presents the analysis of dispersion equation for transverse waves in magnetized electron–positron–ion plasma in which electrons and positrons are counter streaming parallel to the magnetic

Spin-electron-acoustic waves and solitons in high-density degenerate relativistic plasmas

Spin-electron-acoustic waves (sometimes called spin-plasmons) can be found in degenerate electron gases if spin-up electrons and spin-down electrons move relatively each other. Here, we suggest

On the equation of state for the “thermal” part of the spin current: The Pauli principle contribution in the spin wave spectrum in a cold fermion system

Spin evolution opened a large field in quantum plasma research. The spin waves in plasmas were considered among new phenomena considered in spin-1/2 quantum plasmas. The spin density evolution

Quantum kinetic theories in degenerate plasmas

In this review we give an overview of the recent work on quantum kinetic theories of plasmas. We focus, in particular, on the case where the electrons are fully degenerate. For such systems,

The extraordinary waves in spin-1/2 quantum plasma are studied. The evolutions of spin-up and spin-down electrons are considered separately. Hence, the separate spin evolution quantum hydrodynamics

We examine the properties of linear electrostatic waves in unmagnetised quantum and classical plasmas consisting of one or two populations of electrons with analytically tractable distribution
