title: Spin shift register from a one-dimensional atomic chain.
abstract: A spin shift register is described. It is composed of a one-dimensional chain of N identical atoms which each have an electronic spin state with S=1/2. When an additional electron is conducted down the chain, it shifts the spin information by one atom. The spin shift register (SSR) can be used as a computer memory device.
