  1. Superconducting Pinning with Artificially Prepared NanostructuresIvan K. Schuller, UCSD, DMR 03-53729 a a Quasiperiodicpinning potentials BASIC RESEARCH Issue: What happens when periodic and quasiperiodic (or self similar) lattices interact ? Model system: Periodic Elastic Vortex Lattice interacting with a Quasiperiodic Rigid Pinning Lattice Relevance to: Plasma Physics, Epitaxial Growth,Devices Method: Resistivity vs. Magnetic Field Results: Minima reflect the strength of the interaction Fibonacci array RESULTS Scientific: Relevance of correlation lengths in matching phenomena. Distinguish Local vs. Collective matching Educational: Training ground for your researchers in high technology areas. Practical: Papers, Invited talks, PhD theses, Movies, Awards Collaborations: National- Argonne, West Virginia U., International- Spain, Argentina, Belgium Fractal array

  2. Periodic Pinning in SuperconductorsIvan K. Schuller, University of California San Diego, DMR 98-01921 Educational: 1 REU student Summer 2006 1 Undergraduate Student 1 Graduate Student 3 Postdoctoral Fellows Ideal training ground for young researcher who will become the technologists of tomorrow. Brief summary of outreach activities: -Invited Talks: International Meetings, Research Organizations, Museums, Science Journalists, Public Lectures -Major Awards: DOE-Lawrence, MRS Medal, Honorary Doctorate, EMMY, TELLY -Movie: “When Things Get Small” -Web Pages:http//:ischuller.ucsd.edu -International Collaboration: Spain, Argentina, Belgium Figures: Example of the magnetic arrays, the lithography process and the effect on the resistivity of a superconductor.
