Testing Koopmans spectral functionals on the analytically-solvable Hooke's atom

Koopmans spectral functionals are a class of orbital-density-dependent functionals designed to accurately predict spectroscopic properties. They do so markedly better than their...库普曼斯谱泛函（Koopmans spectral functionals）是一类专为精准预测光谱性质而设计的轨道密度依赖泛函，其表现显著优于其……
