Erratum: Comment on “2-Channel Kondo Scaling in Conductance Signals from 2-Level Tunneling Systems” [Phys. Rev. Lett. 75, 769 (1995)] Academic Article uri icon


  • We incorrectly claimed quantitative agreement with no free parameters with the data of Ralph et al.[1]. In effect, a free scaling factor was included in our fit to their data, because of an improper use of the temperature-dependent conductance to normalize the differential conductance data [2]. A portion of Fig. 1 with the correct no-free-parameters curve and the curve with the free scaling factor is presented here. Our discussion of the relevance of the two-channel Kondo interpretation to the data is not affected by this error.
