Quasiperiodic pinning 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
