hi, I am searching for a software or library that can handle operator
algebra in quantum mechanics. For example, I would like to caculate
the commutator [a,H], where the Hamiltonian "H"=\epsilon a^{\dag}a,
and "a" is annihilation operator for, say, an osilator. I tried
GiNaC, and read much documentation, and get little
clue. I wonder if there is a direct implementation of these kind of
operator algebra in GiNaC.
Thank you in advance.
