This project takes advantage of the close synergy between the Institute national de la recherche scientifique (INRS) and the industrial partners, Axis Photonique and Amplitude, to explore how light may be used as an efficient "knob" to control the electronic properties of quantum materials and drive the emergence of new phases of matter with no equilibrium counterpart. Since new technological developments in industry are often fueled by basic research in fundamental and applied physics, the control of the dynamical properties of quantum materials on-demand will impact our society by promoting important developments in the design and optimization of new optoelectronic devices for quantum information and telecommunication.This project will be carried out at the Advanced Laser Light Source (ALLS) international user facility at INRS. By capitalizing on the know-how and technical support of our industrial partners, as well as the support of PRIMA Quebec, we will develop and commission a time- and angle-resolved photoemission (TR-ARPES) endstation that will offer unprecedented access to how electrons react and reorganize upon intense light excitations inside matter. To achieve this project's goals, this academia-industry partnership will develop novel instrumentation and characterization tools to make the TR-ARPES endstation at ALLS unique worldwide and enable cutting-edge investigations of light-driven properties of quantum materials with momentum, binding energy, and time resolutions. The technical know-how gained by our industrial partners throughout the project will impact their commercial potential by enabling them to improve their portfolio and design new products for the characterization of complex materials. Moreover, this research will establish ALLS as a Canadian hub for the research and training of personnel in the light control of quantum matter.
