$ν= 1/2 $附近量子霍尔双电层中的费米液体效应

Fermi-liquid effects in the transresistivity in quantum Hall double layers near $ν= 1/2 $

Natalya A. Zimbovskaya

摘要:

本文从理论上研究了量子霍尔体系中两个平行的二维电子气层在朗道能级半满附近的库仑阻力跨阻随温度和磁场的变化关系。结果表明,费米液体之间的相互作用的相关准粒子可以给一个显着的影响的transresistance,提供其独立的层间距的间距在实验中报道的值。所得结果与实验结果一致。

英文摘要:

Here, we present theoretical studies of the temperature and magnetic field dependences of the Coulomb drag transresistivity between two parallel layers of two dimensional electron gases in quantum Hall regime near half filling of the lowest Landau level. It is shown that Fermi-liquid interactions between the relevant quasiparticles could give a significant effect on the transresistivity, providing its independence of the interlayer spacing for spacings taking on values reported in the experiments. Obtained results agree with the experimental evidence.
