Аннотация:Separated spin-up and spin-down quantum kinetics is derived for more detailed research of the
spin-electron acoustic waves (SEAWs). This kinetic theory allows us to obtain the spectrum of the
SEAWs including the effects of occupation of quantum states more accurately than the quantum
hydrodynamic theory. We derive and apply the quantum kinetic theory to calculate the Landau
damping of the SEAWs. We consider the contribution of ions dynamics into the SEAW spectrum.
We obtain the contribution of ions in the Landau damping in the temperature regime of classic
ions. Kinetic analysis for the ion-acoustic, zero sound, and Langmuir waves at the separated spin-up
and spin-down electron dynamics is presented as well.
