1 Materials Research Network – Collaborative Research: Decoherence, Correlations and Spin Effects on Nanostructured Materials. NSF-DMR Nancy Sandler1, Sergio E. Ulloa1, Kevin Ingersent2, and George Martins3 1Ohio Univ., 2Univ. of Florida-Gainsville, 3Oakland Univ. Sending or blocking current through a device with three quantum dots depends on their geometrical configuration and connections to leads. When 3 dots are aligned, with two connected to external leads (L and R) current flows if the dots are in resonance. Attaching a third lead (P) introduces decoherence and reduces the current. These results may have applications in the design of entangled quantum bits useful for quantum encryption codes. E. Vernek et al. In progress.

Ulloa1, Kevin Ingersent2, and George Martins3 1Ohio Univ., 2Univ. of Florida-Gainsville, 3Oakland Univ. Education: Projects included in this grant are within the research areas of several doctoral students from Brazil (Ginetom Diniz), Florida (Brian Lane), and Ohio (Ahn Ngo and Gregory Petersen) Ahn Ginetom Brian Gregory Postdoctoral fellows Mehdi Zarea, Edson Vernek and Carlos Büsser are actively working on different topics that have resulted in publications. They also presented their results in various national and international conferences. Mehdi presents a poster on graphene ribbons at the OU-CMSS science poster competition. Edson Carlos Büsser (Brazil/US) held the position of “traveling postdoctoral fellow” commuting between Oakland Univ. and OU. Carlos
