Demonstration of Floquet engineering in quantum materials via time- and angle-resolved photoemission spectroscopy

该项目利用国家科学研究所（INRS）与工业合作伙伴Axis Photonique和Amplitude之间的密切协同作用，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，并推动物质的新阶段的出现，而没有平衡对应物。由于基础物理和应用物理的基础研究通常会推动工业领域的新技术发展，因此按需控制量子材料的动力学特性将通过促进量子信息和通信的新型光电器件的设计和优化的重要发展来影响我们的社会。该项目将在INRS的先进激光光源（ALLS）国际用户设施中进行。通过利用我们的工业合作伙伴的专业知识和技术支持，以及PRIMA魁北克的支持，我们将开发和委托一个时间和角度分辨光电发射（TR-ARPES）终端站，该终端站将提供前所未有的访问，以了解电子如何在物质内部的强光激发下反应和重组。为了实现该项目的目标，该公司与行业的合作伙伴关系将开发新型仪器和表征工具，使ALLS的TR-ARPES终端站在全球范围内独一无二，并能够对量子材料的光驱动特性进行前沿研究，包括动量，结合能和时间分辨率。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进其产品组合并设计用于表征复杂材料的新产品来影响其商业潜力。此外，这项研究将使ALLS成为加拿大研究和培训量子物质光控制人员的中心。

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.
