We study the ground-state energy of fully spin-polarized coupled electron layers, with zero and finite width of the layers, embedded in a uniform neutralizing background at temperature T = 0. The correlations are treated within the quantum or dynamical version of Singwi, Tosi, Land and Sjölander (qSTLS) theory as a function of carrier density and layer spacing. Results are compared with the recent diffusion Monte Carlo (DMC) and variational Monte Carlo (VMC) simulation studies of spin-polarized coupled electron layers with zero width. The spin-polarized effect is seen to introduce a marked change in the ground-state energy of the coupled electron layers as compared to the results of unpolarized coupled electron layers with finite width.
