Session 1-2

Abstract

A role of chirality is discussed, being inspired by recent studies on chirality-induced dynamic phenomena with chiral materials. As a manifestation of time-even pseudo scalar, which works as a microscopic chiral term in driven chiral media and hybridizes translational and rotational degrees of freedom, a polarization of angular momenta appears under charge or thermal flow. Notably, such a polarized state of electron spins or atomic vibrations (chiral phonons) is detectable electrically and its robust protection enables non-local spin detection over micrometers and even centimeters in chiral materials. In the talk, I would focus on recent experimental progress on the key findings made with various kinds of chiral inorganic materials [1-9]. A comprehensive understanding of these nontrivial features will clarify the mystery of chirality-induced spin selectivity (CISS).
