摘要:

讨论了单电子晶体管(SET)在零偏压近藤区电导的热依赖性。建立了对称Anderson模型到普适曲线的精确映射。线性,映射由近藤温度和近藤云中的电荷参数化。说明性的数值重整化群的结果,在良好的协议与映射,提出。

英文摘要:

The thermal dependence of the electrical conductance of the single-electron transistor (SET) in the zero-bias Kondo regime is discussed. An exact mapping to the universal curve for the symmetric Anderson model is established. Linear, the mapping is parametrized by the Kondo temperature and the charge in the Kondo cloud. Illustrative numerical renormalization-group results, in excellent agreement with the mapping, are presented.
