7.1.1 Propagator
Definition
Too describe the propagation event from the probability language, A propagator can be used as:
$$G(x_b, t_b; x_a, t_a)= \Sigma{\psi_j(x_b)\psi*_a(x_a)}e{(-i/h)E_j(t_b-t_a)}$$
Recipe
- High dimensional potential energy surface are mapped out first,
- Solve the Schrodinger equation.
-
