I would like to implement the bosonic and fermionic operators (and associated many particle fock states) for the many-particle (non-relativistic) Schrodinger equation. More specifically, like those in Fetter and Walecka many body quantum text. As a start I would be happy with the operators for a single state. This would involve three basic entities: a - annihilation operator adagger - creation operation number state - |n> along with either the commutation relations (bosons) or anticommutation relations. I need to run right now, and I am just starting to play with sympy, but there is a lot of potential for this type of thing with sympy and it could have a significant impact.
