| Outline of Final Research Achievements |
As the manipulation of materials by optical forces, optical tweezers, for example, have been utilized practically and the apparatuses are commercialized. In there, the target material to manipulate is in most cases micrometer-scale particles transparent at the wavelength of the light for manipulation. In the present project, we intentionally utilized the optical characteristics of the material, such as resonance and nonlinear optical effects and polarization characteristics, to develop a variety of manipulation methods. We achieved control of trapping position by UV light for particles containing molecules that undergo structural changes under the UV light illumination, control of trapping force for chiral nanoparticles with circularly polarized light, and so forth. In the environment of superfluid liquid He with almost no viscosity, particle motion was found to be controllable with very weak light.
