Abstract

We present the results from recent studies of field-induced reconfiguration of defect network in Blue phase liquid crystals leading to the formation of new stable lattice structures from their natural self-assembled cubic form [Nat. Materials https://www.nature.com/articles/s41563-019-0512-3]. The dynamical evolution of the defect network and reorientation provide new insights into the underlying mechanisms and roles played by various factors, especially the form of applied field for efficient lattice transformation. Recent studies with optical field derived from CW or short-pulsed lasers further demonstrate the possibility of direct reconfiguration/reorientation of the bulk crystals.
