磁场中多通道近藤点的输运性质

Transport properties of a multichannel Kondo dot in a magnetic field

Christoph B. M. Hörig, Dirk Schuricht

摘要:

研究了多通道近藤量子点在磁场作用下的非平衡输运。我们使用的两圈重整化群方程的精确解推导出的g因子,自旋弛豫率,磁化强度,微分电导的分析结果。我们表明,有限的磁化导致的传导通道之间的耦合,表现在差分电导的附加功能。

英文摘要:

We study the nonequilibrium transport through a multichannel Kondo quantum dot in the presence of a magnetic field. We use the exact solution of the two-loop renormalization group equation to derive analytical results for the g factor, the spin relaxation rates, the magnetization, and the differential conductance. We show that the finite magnetization leads to a coupling between the conduction channels which manifests itself in additional features in the differential conductance.
