    • Nonequilibrium can be addressed via low-order perturbation theory in the hopping, provided the proper unperturbed occupations are taken for the site [N. Sivan, N. S. Wingreen, and Y. Meir (unpublished)].

    • Equation (14) requires that langle O vec >Q=0= 0. Since Q = 0 corresponds to the case where there is no Anderson impurity, all the operators involving the site will satisfy this condition.

    • (Ref. 30), pp., 124–125. In the Dyson equations, additional terms involving the lesser and greater boson and fermion Green functions for the uncoupled site are found to be zero. This reflects the loss of memory of the initial occupation of the site in the coupled system.

    • It would not be correct in (23) to include self-energies for the Green functions in the leads. Such self-energies include a fermion-boson loop which contributes an extra, unwanted factor of exp( - i β λ ).
