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.

在国家科学研究所、能源材料电信研究中心（INRS-EMT）和哈佛大学之间的这一新的国际合作中，我们将结合联合收割机先进的时间分辨光谱技术来研究高温铜酸盐超导体（原型量子材料）的动力学特性。特别是，通过跟踪具有动量和能量分辨率的电子能带结构的瞬态变化，我们将设计定制的超短激光激发，以揭示波动的反铁磁序如何影响空穴掺杂铜氧化物的电子特性，从而出现高温非常规超导性。为了实现这个项目的目标，我们将利用INRS-EMT的先进激光光源（ALLS）用户设施的独特能力，大规模自由电子激光设施，以及这个团队在量子物质超快科学方面的专业知识。这个项目将为INRS和哈佛大学之间的新合作奠定基础，这将导致在量子材料的光控制的新兴领域的高素质人才的培训。此外，这项研究将为实现非常规超导性所需的基本成分提供前所未有的见解，以及如何利用光-物质相互作用来有效地调整量子材料的电子特性，并在超快时间尺度上推动物质的新量子相的出现，从而使加拿大在未来基于量子技术的设计和工程方面处于有利地位。
