自旋半加法器

Spin half-adder

Moumita Patra

摘要:

提出了一种在纳米结中设计自旋半加器的新方案。众所周知,在有限电压下,在非对称环-电极界面结构下,介观环内会出现净循环电流(称为循环电流)。这个环形电流在环的中心感应出有限的磁场。我们利用这一现象构造了一个自旋半加法器。利用环形电流感应的磁场来调节局域自由自旋的取向,通过它们的取向来确定“和”与“进位”的输出态。所有输出都是基于自旋的,因此结果以原子方式存储在系统中。我们还说明了我们提出的模型的实验可能性。

英文摘要:

A new proposal is given to design a spin half-adder in a nano-junction. It is well known that at finite voltage a net circulating current (known as circular current) appears within a mesoscopic ring under asymmetric ring-to-electrode interface configuration. This circular current induces a finite magnetic field at the center of the ring. We utilize this phenomenon to construct a spin half adder. The circular current induced magnetic field is used to regulate the alignments of local free spins, by their orientations we specify the output states of the `sum' and `carry'. All the outputs are spin based, therefore the results get atomically stored in the system. We also illustrate the experimental possibilities of our proposed model.
