Yes, you can define bond and site operators for these and then measure their averages separately.

Hi all, Is it possible to split the total energy calculated by alps into their individual components?

For example, in the case of the Hubbard model I will want to know how to split the kinetic energy and the potential energy terms in ALPS code.u know the total hamiltonian

H=H_hopping(Kinetic term)+H_U(potential term),

when one does the exact diagonization or DMRG,it gives the total energy but I want to calculate the individual energy.

Can anyone help?

Thanks.
