How to integrate the wavefunction

WebThe idea is simply that the wavefunction adjusts itself until the particle has the least possible total average energy. It can be shown that the right-hand side of the expression for the energy above will be a minimum if and only if the expression in brackets is given like so: 1 --- 2 d 2 ---- d x2 ( x) + V (x) (x) = E ( x) For every x. WebIn quantum mechanics, the variational method is one way of finding approximations to the lowest energy eigenstate or ground state, and some excited states.This allows calculating approximate wavefunctions such as molecular orbitals. The basis for this method is the variational principle.. The method consists of choosing a "trial wavefunction" depending …
