28. The possibility that a resonant state associated to a weakly coupled atom could give rise to a quantized conductance has been suggested by S. Ciraci, E. Tekman, A. Baratoff, and I. P. Batra, Phys. Rev. B 46, 10 411 (1992). Notice, however, that in our theory sharp resonances arise by a different mechanism.
