I think you forgot to put from sympy import S at the top. Did I get it right that you calculate the ground state energy of the 1D infinite potential well of width $a$ with a perturbation which is linear in $x$, up to second order in perturbation? I think in general your code is fine. What you might want to do is - have V an operator - same for the unpertubed Hamiltonian H - being able to write those operators in matrix form in a particular basis - find the basis which diagonalizes H - use this basis to represent H and V in matrix forms - compute perturbation theory to first, second, etc. order by looking up the matrix forms - make it general enough to handle degenerate cases I think some of this is possible already, but I haven't looked deeply into it. -- You received this message because you are subscribed to the Google Groups "sympy" group.
