Mott materials for artificial intelligence

The human brain has about 10¹¹ neurons and 10¹⁵ synapses and needs just about ten watts. That degree of interconnection and power e ciency cannot be achieved with silicon electronics. A new disruptive technology made up of neural networks is required. The implementation of arti cial synapses and arti cial neurons remains however a big challenge. Our team has shown that neurons could be made with quantum materials known as Mott insulators. We aim at a decisive theoretical understanding of out-of- equilibrium physics governing the Mott insulators and how they can form neuromorphic networks.
