Project description
Study investigates how electromagnetic fields affect molecular magnetic behaviour
Funded by the European Research Council, the QED-Spin project aims to study quantum field (light) interactions with the electronic and nuclear spins of molecular systems. To this end, researchers will develop for the first time accurate ab initio techniques to describe, at the same time, the quantum behaviour of electrons, nuclei and photons, including also their magnetic and spin properties. The proposed techniques should result in novel strategies for implementing quantum computers, increased control over the photochemistry of molecules and the formulation of new and more selective spectroscopic techniques for chiral systems.
Objective
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.
