Spin half-adder
Abstract
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.
