- W2063426107 abstract "We calculate precise correlation energies of ground and low-lying excited states in circular parabolic quantum dots containing $N=2--20$ electrons by means of a configuration interaction (CI) method with a numerical, mean-field basis set. All excitations are allowed for $2ensuremath{le}Nensuremath{le}7$ (full CI), while up to hextuple excitations are included for $N=8,9$, and up to pentuple excitations for $10ensuremath{le}Nensuremath{le}20$. The energies are extrapolated to the limit of basis-set completeness and the truncation error due to restricting the number of Slater determinants is monitored. For high electron densities (Wigner-Seitz radius ${r}_{s}ensuremath{approx}1.7{a}_{0}^{ensuremath{ast}}$), the approach achieves errors of order $0.3text{ }{text{mHa}}^{ensuremath{ast}}$ for $N=3$, a few ${text{mHa}}^{ensuremath{ast}}$ for $N=6--9$, rising to about $100text{ }{text{mHa}}^{ensuremath{ast}}$ for $N=20$. A comparison is made with recent quantum Monte Carlo calculations." @default.
