摘要: Abstract We study the effect of finite width on ground-state a spin-polarized electron–electron quantum bilayers (EEBL) system at temperature T=0. Correlations among carriers are treated beyond static mean-field theories by using or dynamical version Singwi, Tosi, Land and Sjolander (qSTLS) theory. Numerical results presented for pair-correlation function, energy, density susceptibility, local-field correction factor as function parameter rsl interlayer spacing d. Interestingly, we find that inclusion lowered critical density, onset Wigner crystal (WC) ground-state, compared to similar recent EEBL without effect. Further, spin-polarization is seen introduce marked change in energy unpolarized with width. Results energies also diffusion Monte Carlo (DMC) variational (VMC) simulation studies zero
