摘要: 讨论量子点中对称性限制, 揭示了其与电子构形和幻角动量间的内在联系, 即量子点的电子构形选择高度对称的几何图形; 由于几何图形的对称性限制, 只有幻角动量的态才可访问这些几何图形.
关键词: 对称性限制, 量子点, 电子构形, 幻角动量
Abstract: Symmetry constraint in quantum dots is discussed. Inherence relation among symmetry constraint, electronic configuration and magic angular momentum is revealed, i.e., highly symmetrical geometry graphs are pursued by the electronic configurations of quantum dots. Owing to the symmetry constraint, only the states having magic angular momentum can get access to the graphs.
Key words: symmetry constraint, quantum dot, electronic configuration, magic angular momentum
