Throughout this new international collaboration between the Institut National de la Recherche Scientifique, Énergie Matériaux Télécommunications Research Centre (INRS-EMT), and Harvard University, we will combine advanced time-resolved spectroscopy techniques to investigate the dynamical properties of high-temperature cuprate superconductors, the prototypical quantum materials. In particular, by tracking transient changes of the electronic band structure with momentum- and energy-resolution, we will design tailored ultrashort laser excitations to unveil how fluctuating antiferromagnetic order impacts the electronic properties of hole-doped cuprates, thus consequently, the emergence of high-temperature unconventional superconductivity. To achieve this project's goals, we will take advantage of the unique capabilities of the Advanced Laser Light Source (ALLS) user facility at INRS-EMT, large-scale free-electron laser facilities, as well as the expertise of this team in ultrafast science of quantum matter.This project will seed a new collaboration between INRS and Harvard University, which will result in the training of highly qualified personnel in the emergent field of light control of quantum materials. Furthermore, this research will offer unprecedented insights into the fundamental ingredients needed to achieve unconventional superconductivity, as well as how light-matter interaction can be used to effectively tune the electronic properties of quantum materials and drive the emergence of novel quantum phases of matter on ultrafast timescales, thus positioning Canada in a privileged position for the design and engineering of the quantum-based technology of tomorrow.
