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.

该项目利用了研究所国家de la recherche Scientifique（INRS）与工业伙伴，轴光子和振幅之间的紧密协同作用，探索如何将光用作有效的“旋钮”来控制量子材料的电子特性，并驱动与Equilibribibium Aunperpart的新阶段的出现。 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.通过利用我们的工业伙伴的知识和技术支持以及Prima Quebec的支持，我们将开发和委托使用时间和角度分辨的光发射（TR-ARPES）终端站，该终点站将为您对电子的反应和重新组织对内部的强烈的兴奋方式进​​行反应和重新组织。为了实现该项目的目标，这种学术界 - 行业合作伙伴关系将开发新颖的工具和表征工具，以使全球独特的Tr-Arpes终端站在全球范围内，并能够以动量，结合能量和时间分辨率和时间分辨率对量子材料的轻度驱动材料进行尖端调查。我们的工业合作伙伴在整个项目中获得的技术知识将通过使他们能够改善其投资组合并设计新产品以表征复杂材料来影响其商业潜力。此外，这项研究将成为加拿大枢纽，以研究和培训量子问题的人员。
