Outline of Final Research Achievements

We performed the elucidation of mechanism, the extension of scope, and the generalization with respect to “preferential enrichment” and “positive magneto-LC effects”, which are unique chemical phenomena arising from the phase transition of chiral organic compounds and were discovered by us using a molecular chirality or an electron spin as a probe. Consequently, these phenomena have been found to be the events of macroscopic complexity phenomena which originate from the symmetry-breaking caused by the phase transition between nonequilibrium metastable (chaotic) states.
