title = "Spiral-structured crystal of ethylenediamine sulfate fabricated by optical trapping",
abstract = "Optical trapping realizes the formation of a unique spiral-structured crystal of ethylenediamine sulfate (EDS). When a continuous-wave laser beam of 1064 nm is tightly focused at the air/solution interface of EDS aqueous saturated solution, the EDS crystal is induced at the laser focus and is grown by further laser irradiation, and the crystal growth with a spiral structure is observed. Intriguingly, the preliminary experimental data suggest that the growth direction of spiral- structured crystal corresponds to the handedness of circular polarization of the incident light. We propose that the growth direction is determined by the transfer of the angular momentum of incident circularly polarized laser to the growing crystal due to crystal birefringence.",
