Researchers using determinant quantum Monte Carlo simulations have demonstrated that peak superconductivity in two-dimensional models does not occur at the theoretically expected Van Hove points. This finding challenges weak-coupling BCS theory predictions and indicates that optimal transition temperatures arise from intermediate interaction strengths rather than extreme coupling values. The study provides critical insights into strong-coupling mechanisms, suggesting that maximizing electronic density singularities alone is insufficient for achieving maximum superconducting performance.
