关于“平行T形双量子点的零温电导”的评论[Physica E 39(2007)214,arXiv:0708.1842v1]

Comment on: ``Zero temperature conductance of parallel T-shape double quantum dots'' [Physica E 39 (2007) 214, arXiv:0708.1842v1]

摘要:

在最近的论文[Physica E 39(2007)214,arXiv:0708.1842v1]中,Crisan、Grosu和Tifrea重新研究了通过以T形配置连接到电极的双量子点分子的电导问题。作者得到了一个表达式的电导,不同意以前的结果在文献中。我们指出了他们在推导电导公式时的一个错误,并表明即使对于非相互作用的量子点,它也给出了非物理的结果。

英文摘要:

In a recent paper [Physica E 39 (2007) 214, arXiv:0708.1842v1] Crisan, Grosu and Tifrea revisited the problem of the conductance through a double quantum dot molecule connected to electrodes in a T-shape configuration. The authors obtained an expression for the conductance that disagrees with previous results in the literature. We point out an error in their derivation of the conductance formula and show that it gives unphysical results even for non-interacting quantum dots.
