Light-based understanding of magneto-chiral interactions and chirality-induced spin selectivity
Keywords
Chirality ; spintronics ; orbitronics, chiroptics ; CISS ; MChA
Summary
Chirality-induced spin selectivity (CISS) has over the recent years become an intense interdisciplinary research topic. The very strong enantioselective electron spin – chiral material interaction observed represents both an intriguing fundamental question and the promise of an extensive range of large-scale applications, ranging from spintronic devices like circularly polarized light emitting diodes and magneto-chiral optical memories, up to enantiomer separation and efficient electrolysis for hydrogen generation. However, so far, no satisfactory explanation for the strong CISS effects has been found, which holds back the realization of its enormous application potential. Another manifestation of the interaction between chirality and magnetism is magneto-chiral anisotropy (MChA), which has become a prominent representative of the wider class of non-reciprocal transport phenomena in broken-symmetry systems, that play an import role in topological quantum systems and in Berry phase physics.

The LUMINESS project aims to obtain full, quantitative understanding of the CISS effect, determine its relation to MChA, and develop its application potential, all by using advanced chiroptical methods, ranging from microwaves to X-rays, to control electron chirality, both spin- and orbital-based, and to study its interaction with custom designed and synthesized chiral molecular materials.
The two main experimental approaches are the study of the generation and transport of photo-electrons with well-defined spin and orbital magnetic moment through custom-designed chiral molecules, layers, and crystals, and the development of novel chiroptical spectroscopic techniques. An important theoretical effort aims to find a quantitative description of the coupling between angular momentum and chirality, and will interpret and guide the experiments.
LUMINESS will bring together the existing CISS and MChA activities in France in a coordinated, collective and structured effort and allow to establish a French leadership in this domain that will realize the potential of the combined actions of chirality and magnetism in opto-electronics, spintronics and orbitronics.
