Which outcome results when numerical instability arises evaluating electronic wavefunctions using the Variational Monte Carlo method?

A)Spurious minima within energy landscape
B)Violation of the Pauli exclusion principle
C)Overestimation of kinetic energy
D)Underestimation of electron correlation

💡 Explanation

Spurious minima arise because numerical instability causes erratic energy estimations preventing true ground state convergence through the energy landscape. Therefore, false minima are detected, rather than locating the ground state achieved with an exact evaluation of the wavefunction.
