On the critical temperature of two-channel Kondo model: Reply to cond-mat/0009283

Abstract

We discuss the comment by Zarand and Zawadowski (cond-mat/0009283) on our preprint cond-mat/0007430 where it has been shown that the strong coupling regime for the two-channel Kondo model of two level system can be never realized for any realistic microscopic description. The authors of the comment state that the Kondo temperature can be substantially increased due to electron-hole asymmetry. Here we show by direct calculation that the electron-hole asymmetry does not enter the leading logarithmic approximation. Consequently, we disagree with the aforementioned comment.
