AbraDabraa!,

Is it possible to evolve the given state with time-dependent Hamiltonian H(t)?

The hamiltonian is periodic, namely H(t)=H(t+T)

More details:

1) I need to find the ground state psi*0 of H(0)
2) find psi*t of the Schroedinger eq. with psi

*0 and H(t)*

3) compute the average <psit| O | psi_t> of some operator O

3) compute the average <psi

4) integrate the result over t
