  • Walter Kohn, Jim Klingshirn, UCSB, Visual Distortions in Macular Degeneration: Quantitative Diagnosis and Correction
    back of the eye Most visual information is absorbed as light by the macula then converted into an electrical impulse which moves along the optic nerve into the brain s visual cortex There it is perceived by the patient another miracle Undistorted central vision requires a smooth forward facing macular surface while a wrinkled macular surface causes visual distortions which the present work aims to eliminate or at least mitigate

  • Philip Kim, Columbia University, Bloch, Landau, and Dirac: Hofstadter's Butterfly in Graphene
    into a self similar fractal set of energy spectrum known as Hofstadter s Butterfly Fascinating electron energy spectrum have continued ever since Recent advent of graphene where its Bloch electrons can be described by Dirac fermions provides a new opportunity to investigate this half century old problem experimentally In this presentation I will discuss the experimental realization Hofstadter s Butterfly via substrate engineered graphene under extremely high magnetic fields controlling

  • Paul Hansma, UCSB, Physics, From Broida to Bedside: From Fundamental to Clinical Research on Bone Fracture
    Bone fracture begins with the separation of the mineralized collagen fibrils at nanometer length scales New instruments can now test how well bone resists this nanoscale separation of mineralized collagen fibrils even in living patients The results of these tests distinguish between the bone of patients with and without fractures Thus these instruments have the potential to diagnose bone fragility and to guide the development of therapies for decreasing bone

  • Mark Dennis, University of Bristol, Knotting Nodes of Light
    which are closed loops and others are infinite open lines Computer simulations of random superpositions of plane waves indicate that these lines have the fractal properties of brownian random walks with characteristic scaling of the probability that pairs of loops are linked together Holographically controlled laser beams provide the opportunity to control the form of optical fields and the nodal lines within them Using the theory of fibred knots I
