Summary
TORNADO is an interdisciplinary project combining chemistry, materials science, nanophotonics, optics, and spectroscopy. We aim to understand and control chiral light-matter interactions with potential spin-offs in optoelectronics, asymmetric synthesis, and quantum information processing. The study of chirality at different spatial and temporal scales will enable us to elucidate its role in electronic, photonic, and vibrational dynamics in a variety of systems such as free molecules, supramolecular assemblies, chiral nano-objects, liquid and solid crystals, plasmonic resonators, metasurfaces, and photonic crystals.
Scientific expectations
Managers : Thierry Ruchon & Anne Zehnacker
Chiral photochemical reactions will be probed at femtosecond to nanosecond timescales using photoelectron dichroism to determine the spatial extent and lifetime of chirality. Other optical spectroscopies from the visible to the extreme UV will be used to reveal electronic chirality on the nanometre scale and to distinguish the effect of point chirality from that of supramolecular chirality. The influence of the orbital angular momentum of light will be studied in chiral molecules, nanostructures, topological materials, and magnetic structures using helical dichroism, photoelectron imaging, or ultrafast electron microscopy (400 fs with 1 nm resolution).
Managers : Cyriaque Genet & Reiko Oda
3D chiral light with spin and orbital angular momentum will control chiral electronic dynamics on the attosecond scale, and the synthesis of new chiral transition metal complexes will create enantiomerically pure, circularly efficient polarized light emitters for chiral optoelectronics. In a dual experimental and theoretical effort, we will target asymmetric polaritonic chemistry by exploring strong chiral light-matter coupling in cavities. Valley pseudospin dynamics in van der Waals heterostructures based on transition metal dichalcogenides coupled to an optical spin-orbit resonator will also be investigated.
Managers : Etienne Brasselet & Jeanne Crassous
Using spin-resolved laser-induced electron diffraction, we will measure chirality-induced spin selectivity to reveal the fundamental processes involved. In liquid crystals, we will study the transfer of the topological properties of light to matter to produce novel optical sensors and memories. We will also induce new topological properties at the electronic level in transition metal dichalcogenides, which could be a big step towards robust platforms for quantum information storage and processing. Finally, the strong chiral light-matter coupling of topological edge modes will be studied theoretically, with potentially significant applications for information routing in quantum networks.
