Advancements in Liquid Crystals: Optical Vortices and Smart Fluids for Future Technologies

This report highlights groundbreaking research from ICAM-I2CAM, led by Daniel L. Cox at UC Davis, focusing on the switching capabilities of liquid crystals. Researchers at CU-Boulder have demonstrated that optical vortices can achieve local multi-stable switching of topological structures in liquid crystals, paving the way for innovative applications in consumer devices and information displays. Additionally, these materials serve as "smart" fluids facilitating the assembly of nano- and micro-sized particles into complex structures, opening new frontiers in photonic architecture and advanced material science education globally through programs like I-CAMP.

Presentation Transcript

  1. International Institute for Complex Adaptive Matter (ICAM-I2CAM) Daniel L. Cox, University of California-Davis, DMR 0844115 Switching of liquid crystals forms the basis for the modern display technologies and applications such as label-free biodetection and laser beam steering. ICAM-I2CAM researchers at CU-Boulder demonstrate that optical vortices are capable of local multi-stable switching of topological structures in liquid crystals. This research can lead to new ways of multistable structuring of complex photonic architectures in liquid crystals and applications ranging from all-optical consumer devices to novel information displays. Another emerging application of liquid crystals utilizes them as “smart” fluids that mediate inter-particle interactions assembling the nano- and micro-sized colloidal particles into superstructures according to the particles’ shape.

  2. International Institute for Complex Adaptive Matter (ICAM-I2CAM) Daniel L. Cox, University of California-Davis, DMR 0844115 Inter-Continental Advanced Materials & Photonics Summer School (I-CAMP): “One world – one dream”: Advanced Education at the Interface of Photonics & and Materials Sciences ICAM organizes a series of international summer schools such as I-CAMP’09 held in Hangzhou-Shanghai-Qingdao-Beijing, China: http://icamconferences.org/i-camp/ and I-CAMP’10 planned to take place in Sydney-Brisbane, Australia. The major goal of these schools is tocombine advanced graduate-level education with learning about diverse cultures around the World. All lectures are webcast in real time (including those from China in 2009) and then video-archived on the school web pages. ICAM-I2CAM is organizing a new REU Program providing international research experience for undergraduates.
