WebApr 13, 2024 · Nature is not always ambidextrous: it sometimes favors one hand, e.g., in the chirality of amino acids. In a recent issue of Cell Reports Physical Science, Wang and Sugiyama demonstrate the transformation of a crystal from achiral to chiral, where the hand of the crystal can be selected by the hand of circularly polarized light. WebWe observe chiral domains in the paraelectric nematic phase of a chemically achiral ferronematic. This behaviour is due to spontaneous symmetry breaking arising from saddle splay elasticity and helical segregation, the first example of this
