CAREER: Quantum dynamics of spin in molecular magnetsEnrique del Barco, University of Central Florida, DMR 0747587 The integrated research and educational program of this CAREER project has been focused on the development of the experimental and educational tools for the study, understanding and dissemination of the quantum dynamics of nanometer sized magnets under a broad range of experimental conditions. Recent results (published in PRL[1]) have provided the first evidence of asymmetric Berry phase quantum interference patterns on the quantum tunneling of the magnetization in single-molecule magnets. FIG. 2: Contour plots of the QTM probabilities for resonances k = 0 and k = 1 as a function of the transverse field magnitude, HT, and direction, φ. All of the k = 0 minima lie approximately along the φ = 0 axis, whereas the k = 1 minima appear at different orientations for different HT values [1] H. M. Quddusi, J. Liu, S. Singh, K. J.

Quantum dynamics of spin in molecular magnetsEnrique del Barco, University of Central Florida, DMR 0747587 With the help of high school students, we have launched an inter-disciplinary ON-LINE BLOG titled “UCF high-school Science” to bridge the connection between K-12 students in the Central Florida area and nanoscience researchers in local institutions. The blog is maintained almost exclusively by K-12 students, through their own contributions and experiences. The goal is to involve young students into active research projects well before their arrival to college. During the duration of the project, more than 20 high school students have found a research project with a group at UCF thanks to the blog, which serves to canalize communications between students and UCF faculty. A interactive blog to attract K-12 students of the Central Florida area to the recent advances in nanoscience research has been created as part of the education program of this CAREER project VISIT www.highshoolscience.ucf.edu
