Argonne Physics Division Seminar - 20 Feb 2007

After reviewing the history, beginning in the 1660s, of lines of phase and polarization singularity in light and other waves, I will describe our present understanding of their geometry, and several recent applications: to spiral phase plates (vortex choreography), vortex knots and links, the optics of biaxial crystals that are chiral and absorbing, and quantum cores of the singularities.
