Rich dynamic behavior of solitons has attracted a great deal of interest in fields of physics ranging from fluid dynamics to optics. Unlike in those fields, topological solitons are extremely accessible when using liquid crystals as a host medium, providing a model experimental system for discovering the physics behind. The research presented in this thesis studied the photo-tunable dynamics of a topological solitonic field configuration dubbed “torons” in chiral nematic liquid crystals, and we show that precise-controlling of the toron motions, forming reconfigurable lattice-structures of torons, and potentially controlling the electric-driven toron “squirming” motions, can be achieved with light exposure.
