两个相互作用导体的互相关

Cross-correlation of two interacting conductors

M. C. Goorden, M. Buttiker

摘要:

我们计算了两个弱相互作用介观导体的电流互相关。我们的推导是基于在Goorden和Büttiker [Phys. Rev. Lett. { \bf 99},146801(2007)]。我们包括费米海的理论,并显示如何计算运输量,特别是互相关的线索。我们研究了两个混沌量子点的零频电流互相关,并利用随机矩阵理论计算了其涨落的大小。

英文摘要:

We calculate the current cross-correlation for two weakly interacting mesoscopic conductors. Our derivation is based on the two-particle scattering matrix derived in Goorden and Büttiker [Phys. Rev. Lett. {\bf 99}, 146801 (2007)]. We include the Fermi sea in the leads into the theory and show how to calculate transport quantities and specifically cross-correlations. We focus on the zero-frequency current cross-correlation of two chaotic quantum dots and calculate the magnitude of its fluctuations with the help of Random Matrix Theory.
