Kondo effect 基本例句 康多效应 We have demonstrated that theKondo effectexerted by a magnetic ion depends on its chemical environment.报道了如何通过改变单个磁性离子的化学环境来调控其自旋性质. In the interaction regime, theKondo effectis influenced significantly by the presence of a precessing magnetic field.当计入库仑关联相互作用后 ;近藤共振效应受外部进动磁场的影响很强 . For example, recently theKondo effecthas been controlled in quantum dot systems by changing their charging and hence the spin state of the dots.金属酞菁和卟啉类的平面大环配合物分子由于其中心可以内嵌带有确定自旋的磁性原子,可以作为单个局域自旋的良好载体。 Now we show here that theKondo effectarising from magnetic ions on the surface of a nonmagnetic conductor can be controlled by changing their chemical environment.因此我们选择了钴酞菁这一带有单个磁性离子的平面大环配合物分子,对其吸附到表面的单分子体系进行了仔细的研究。 We study the equilibrium and non-equilibriumKondo effectin series-coupled double quantum dots connected to ferromagnetic leads both in parallel and antiparallel configurations.研究了与铁磁电极耦合的串连双量子点中的平衡和非平衡近藤效应,同时考虑了两侧电极中自旋极化的态密度为平行和反平行的情况。 Our results show that when the system goes into the strong coupling regime, two parallel dots can be coupled coherently, which leads to an enhancedKondo effectand a giant persistent current emerging in this system.研究的结果表明;在这个系统中;当两个量子点处于强耦合时;两个量子点可以相干耦合成一个人造分子;导致一个增强的Kondo效应和超强持续电流的出现. |
