A deeper understanding of the correlated behaviour of charged particles is nowadays cru- cial for advances in the fields of quantum electronics, nanotechnology and in physics in general. Currently under extensive experimental study are ultracold charged boson gases. Electrons, as realised in two-dimensional (2D) conducting layers and a hot topic for the past few decades, remain an even higher challenge due to Pauli exclusion. This work merges both issues. I calculate ground state properties of multi-component bulk bosons as well as spin polarised 3D and 2D electron systems. Emphasis is put on the pair distribution function g(r) and the static structure factor S(k), which entirely determine the structure of a many-particle system in real and...
