【 摘 要 】
We numerically study the effect of non-symmetry dictated nodes (NSDN) on electron correlation effects for spinless electrons. We ï¬nd that repulsive interaction between electrons can enhance the overlap between nearest neighbors in the tight binding Hamiltonian, in the presence of NSDN. Normally, in the absence of NSDN, attractive interaction between electrons give such an effect and repulsive interaction gives the opposite effect.
