库仑阻塞的密度泛函描述:绝热或动态交换相关?

Density functional description of Coulomb blockade: Adiabatic or dynamic exchange-correlation?

Zhenfei Liu, Kieron Burke

摘要:

在Kondo温度以上,Anderson结的Kohn-Sham零偏压电导已被证明完全错过库仑阻塞。在一个标准模型的谱函数,我们推导出一个参数化的现场交换相关电位和偏差下降的网站占领的函数,适用于所有的相关强度。我们用我们的研究结果播种怀疑的共同解释所产生的动态交换相关的贡献,这样的修正。

英文摘要:

Above the Kondo temperature, the Kohn-Sham zero-bias conductance of an Anderson junction has been shown to completely miss the Coulomb blockade. Within a standard model for the spectral function, we deduce a parameterization for both the onsite exchange-correlation potential and the bias drop as a function of the site occupation that applies for all correlation strengths. We use our results to sow doubt on the common interpretation of such corrections as arising from dynamical exchange-correlation contributions.
