Description du projet
Une étude examine comment les champs électromagnétiques affectent le comportement magnétique des molécules
Financé par le Conseil européen de la recherche, le projet QED-Spin entend étudier les interactions des champs quantiques (lumière) avec les spins électroniques et nucléaires des systèmes moléculaires. Pour ce faire, les chercheurs développeront pour la première fois des techniques ab initio précises afin de décrire simultanément le comportement quantique des électrons, des noyaux et des photons, y compris leurs propriétés magnétiques et de spin. Les techniques proposées devraient aboutir à de nouvelles stratégies de mise en œuvre des ordinateurs quantiques, à un contrôle accru de la photochimie des molécules et à la formulation de nouvelles techniques spectroscopiques plus sélectives pour les systèmes chiraux.
Objectif
The goal of QED-Spin is to build novel ab initio techniques to reveal effects induced by quantum fields on the spin properties of molecules. Quantum computing and spectroscopic techniques are just two of the main fields that stand to benefit significantly from advancements in spin engineering; a field that is currently at the science frontier both for experiments and quantum many body theory. In this project I will propose new strategies based on strong light-matter coupling to manipulate static and dynamical spin properties of molecules. The mission of QED-Spin is to explore, using advanced theoretical techniques, the phenomena that arise when quantum fields interact with the electronic and nuclear spins of molecular systems and their implications in chemistry, spectroscopy and spintronics. In particular the proposed techniques will represent a significant step forward toward a better manipulation of molecular spin qubits used in quantum information and energy and memory storage. They will also increase our current possibilities of control on the photochemistry of molecular systems. The effects induced on the nuclear spins will bring to the formulation of a novel and more selective nuclear magnetic resonance technique. The developed theoretical and computational techniques will provide, differently from the previously applied model treatments, new tools to quantitatively simulate spin properties of molecules. Combination of cavity quantum electrodynamics and accurate quantum chemistry methodologies will form the basis for the development of novel tools to interpret and design spin properties. Coupled cluster theory, configuration interaction and density matrix renormalization group approaches will be used. I believe that the results of QED-Spin will build the foundations for a new field of research -- cavity spintronics.
