Abstract

Defects in 2D colloidal crystals are of fundamental interests in condensed matter physics as they serve as model systems for systems with topological order and topological phase transitions. Optical tweezers played an essential role in the studies of colloidal defects in the past 20 years. In this talk I will discuss the dynamics of interstitials and vacancies in 2D colloidal crystals. I will discuss the possible new directions in this area.
