Аннотация:Degenerate plasmas with motionless ions show existence of three surface waves: the Langmuir
wave, the electromagnetic wave, and the zeroth sound. Applying the separated spin evolution
quantum hydrodynamics to half-space plasma, we demonstrate the existence of the surface spin-electron
acoustic wave (SSEAW). We study dispersion of the SSEAW. We show that there is
hybridization between the surface Langmuir wave and the SSEAW at rather small spin polarization.
In the hybridization area, the dispersion branches are located close to each other. In
this area, there is a strong interaction between these waves leading to the energy exchange.
Consequently, generating the Langmuir waves with the frequencies close to hybridization area we
can generate the SSEAWs. Thus, we report a method of creation of the spin-electron acoustic
waves.
