Acoustic plasmons and isotropic short-range interaction in two-component electron liquids

Dispersion of acoustic plasmons and isotropic Landau parameters are calculated in three- two-dimensional two-component electron-electron electron-hole liquids at various concentration mass ratios using the Landau-Silin kinetic equation random phase approximation for self-energy. It is shown that mode propagation strength quasiparticle interaction determined by intercomponent screening asymmetric with respect to charge composition liquid. The well-defined plasmon-zero sound arises strong difference concentrations between components its renormalization short-range exchange-correlation negligible. plasmon mediated interparticle effective fast component weak both electron parabolic dispersion, so associated plasmonic superconductivity formation plasmarons unfavorable.
