Grant: Canada Research Chairs

Quantum materials encompass solid systems that exhibit unique and technologically relevant electronic, magnetic, and topological properties that cannot be explained by basic quantum mechanical models. It is well established that these materials' exotic properties arise from the way their electrons interact, i.e., how each electron is influenced by all the other electrons around it. Moreover, these electron interactions occur on ultrafast time scales, commonly captured by the femtosecond unit, which equals one-millionth of a billionth of a second. To further promote quantum-based technological breakthroughs, it is essential to achieve a comprehensive understanding of quantum materials' fundamental electronic properties on their intrinsic ultrafast time scales. This Canada Research Chair program aims to comprehend, and ultimately control, the properties of quantum materials in a dynamic fashion. Prof. Boschini will employ advanced ultrafast techniques, especially time- and angle-resolved photoemission (TR-ARPES) spectroscopy, to fulfill the objectives of this program. Prof. Boschini heads a TR-ARPES system with unique working parameters at INRS-EMT, providing direct access to ultrafast electron dynamics of quantum materials by means of intense, long-wavelength light excitation. Three primary scientific objectives are defined for this ambitious program: (i) engineering light excitations capable of propelling new and unexplored phases of matter in Dirac-like materials, including graphene; (ii) uncovering the crucial role of dynamic electron interactions in defining the electronic properties of unconventional superconductors; (iii) developing a novel photoemission-based technique that will enable unprecedented access to electron interactions in solids. This program also has at its heart the inclusive and equitable training of future experts in ultrafast quantum materials science and related quantum technologies. This strategic goal aligns with the Quebec and Canadian governments' objective of promoting economic growth and fostering the next quantum revolution. To this end, highly qualified personnel will have access to and develop unique and advanced scientific instruments and will be exposed to innovative scientific research and emerging technologies. The program is aligned with the scientific programs of both INRS and INRS-EMT, and INRS will provide all necessary support to Prof. Boschini to attain the program's objectives.
