Correlations in charged fermion-boson mixture in dimensionalities D=2 and D=3

We numerically study the correlation effects in a two-component charged fermion-boson mixture at zero temperature investigating the role played by the statistical effects and Coulomb correlations in a model with different fermion and boson mass ratios in two and three dimensions. The local-field factors describing the correlation effects and collective excitation modes are determined through the self-consistent scheme. We find that the effects of correlations and statistics are more pronounced in two-dimensional mixtures
