Introduction,In the many-electron problem, one is focused on solving the Schrödinger equation which for stationary states Ψ reads:.where Ĥ is the many-electron Hamiltonian which in the non-relativistic case, under the Born-Oppenheimer approximation, for N electrons and M atoms reads:fallible 发表于 2025-3-29 05:52:57
