Elasticity, Topology, and Geometry: FC Frank’s Legacy on the Field of Liquid Crystals.
Professor Randall Kamien (University of Pennsylvania, U.S.)
Frank Lecture Theatre, School of Physics, University of Bristol, Tyndall Avenue, Bristol BS8 1TL
In 1958 Sir Charles Frank delivered a landmark paper to the Faraday Society to “urge the revival of experimental interest in the subject” of liquid crystals. Not only did he formulate the fundamental elasticity theory that governs nematic liquid crystals and provide a topological interpretation for the defect patterns seen in liquid crystals, but he also anticipated the complex geometries that can arise in more ordered liquid crystalline phases. I will review the story of disinclinations and dislocations in the context of the smectic state, taking as a starting point Frank’s discussion.
This ‘F.C. Frank Lecture’ will be followed immediately by a reception, sponsored by the Institute of Physics, South West Branch, in the foyer outside the Powell Theatre.
All are welcome.
