Chiral Interactions Between Light and Materials

Akitsu T

In chemistry, biology, and physics, (a)symmetry or “chirality” is an important concept in nature. However, there are only a few examples of chiral interactions between light and (photo-sensitive) materials. In order to know the overview the light-induced chirality of different materials at present level, interactions or the effects on “chirality” of “materials” by “(topological) light”, like the optical vortex, as well as circularly polarized light, coherent light (such as laser or free electron laser), or conventional linearly polarized light, will be collected in the Special Issue in Symmetry (published by MDPI), to that presenters of this workshop are strongly suggested to submit., tooIn this Workshop, I would like to compile and compile research results, commentary, reviews etc. that have dealt with (chiroptical) spectroscopy, physical properties (magnets, conductors, nonlinear optics and so on), computational chemistry (of asymmetric organic synthesis) and/or theoretical chemistry and their discussions on chirality. In contrast to circularly polarized light carrying spin angular momentum, for example, optical vortex (topological light of the Laguerre-Gaussian mode) carries orbital angular momentum, as observed by Allen in 1992. And since then, various studies on optical vortex have been reported in view of, predominantly, optical physics. Recently, the optical vortex has been resulted in helical manipulations of soft materials on the surface, as well as the rotation of nanomaterials, due to optical torque of the optical vortex.
