Boulder International Workshop

Light-Controlled Liquid Crystal Complex Adaptive Materials - LC2CAM

August 6 - August 10, 2008

Conference Chairs: Noel A. Clark & Ivan I. Smalyukh University of Colorado at Boulder

The Boulder LC2CAM International Workshop will enable researchers working at the forefronts of materials science & optics to discuss the emerging uses of light for control of ordered soft materials and advances in the use of liquid crystals to control light. Workshop topics include:

  • Laser trapping and manipulation in liquid crystals
  • Tunable and frequency-selective negative-index media
  • Light-induced phase transitions
  • Nonlinear optics of liquid crystals
  • Lasing in liquid crystals
  • Light-controlled surface anchoring phenomena
  • Confocal, multiphoton fluorescence, and CARS microscopy of liquid crystals
  • Liquid crystals for solar cells and light harvesting
  • Holographic polymer dispersed liquid crystals
  • Light-controlled liquid crystalline polymers and elastomers
  • Optics of colloidal and nanostructured systems
  • Sensors and wavefront control devices

The Boulder LC2CAM Workshop will bring together both prominent & junior scientists. Participation of students & postdoctoral fellows is strongly encouraged, and up to 20 fellowships will be awarded to support travel of early-career scientists. The presentations will be webcasted in real time and, in addition to the on-site audience, registered participants around the World will have an opportunity to ask questions.
