Relative difference between that HF and R12-FCI energies as a function of the Coulomb scaling parameter.
Convergence of the ground state energy as a function of number of geminal parameters.
Comparison of the electron-hole recombination enhancement factor from the eh-XCHF calculation with HF and R12-FCI results.
Comparison of the geminal function with the fitted exponential function and R12-FCI wavefunction. The geminal function has been scaled so that the geminal and the R12-FCI curves can be plotted in the same figure.
GTO basis used in HF and eh-XCHF calculations.
STO basis used in the R12-FCI calculations.
Optimized geminal parameters.
Comparison of calculated ground state energy and electron-hole recombination enhancement factor from HF, R12-FCI, and eh-XCHF calculations for the parabolic quantum dot. The Hamiltonian for the dot was defined by setting k = 1/4 in Eq. (23).
