| Summary |
"A thorough investigation was conducted into the six fundamental classes of two coupled Aharonov-Bohm rings that share a finite center common path, when the phase of the electron wave function was modulated by two distinct magnetic fluxes. The coupling is similar to two coupled atoms. The behavior of charge accumulation along the center common path or equivalently the bonding and anti-bonding of the two rings can be achieved as the two applied fluxes are varied. Thus when three external terminals are connected to such coupled rings, the behavior of the electron transport is divided into several classes depending on the number of atoms in each ring and the locations of the terminals. The results are presented in this thesis. The application to electron wave computing circuits is discussed. In particular, a half-adder construction is demonstrated by employing the symmetric and anti-symmetric properties of the transmission of a given terminal when the sign of the flux is changed. The analogy of two coupled rings with respect to two spins allows one to make a further connection with traditional Spintronics-based computing schemes"--Abstract, leaf iii. |
