ExprPtr sequant::mbpt::op::T_pt(std::size_t order, std::size_t K, bool skip1 = false)

Makes sum of perturbed particle-conserving excitation operators up to rank K.

Parameters:

• order – order of perturbation

• K – rank up to which the sum is to be formed

• skip1 – if true, skips single excitations

Pre:

order==1, only first order perturbation is supported now
