TT 32: Focus Session: Spin Phenomena in Chiral Molecular Systems I (joint session O/TT)

Dienstag, 19. März 2024, 10:30–13:15, MA 141

Spin phenomena in monolayers and thin films of enantiopure chiral molecules have recently attracted great attention. These phenomena are attributed to the chiral induced spin selectivity (CISS) effect, which leads to, for instance, different transmissions for the longitudinal orientation of the electron spin through helical molecules arranged with their molecular axes perpendicular to the surface. A microscopic theoretical understanding of the CISS effect has not been achieved so far. Therefore, new tools are being developed to uncover the different influences of electronic structure, spin-orbit coupling, and (chiral) phonons on the CISS effect. Applications have already been demonstrated in spin-directed chemistry, spintronics, and quantum technologies. The purpose of this Focus Session is to review the state-of-the-art and also to report new results.
