Can a Node-Less Wave Function Have Higher Energy than Node-Full Ones?
2022-9-6
“The energy level of an electron state increases as the number of nodes in its wave function increases.” The preceding statement, often found in textbooks, was challenged by our large-scale DFT (density-functional theory) calculations performed for the decavacancy in Si crystal.
