Exploring Quantum Materials with Angle-Resolved Photoemission Spectroscopy (ARPES)

Angle-Resolved Photoemission Spectroscopy (ARPES) is a powerful technique for exploring the microscopic nature of quantum materials. By directly measuring their electronic band structure through the photoemission process, ARPES provides critical insights into the relationship between electronic properties and macroscopic behaviors such as conductivity, magnetism, and optical responses.

This technique has broad applications in modern materials science, including mapping the electronic structures and Fermi surfaces of novel quantum materials, identifying non-trivial surface states in topological insulators, Dirac semimetals, and Weyl semimetals, measuring band gaps and pseudogaps in superconductors, and investigating strong electron-electron interactions in correlated systems.

This presentation will provide a concise overview of the theoretical aspects of ARPES. I will also present experimental perspectives, illustrating its versatility through applications in quantum materials.

Prof. Cris Adriano is an Associate Professor in the Département de Physique at the Université de Sherbrooke. Experimental condensed matter physicist, with experience in growing and characterizing quantum materials. Currently interested in materials displaying nontrivial topology where the inherently quantum effects dominate. Research interests include topological insulators, Dirac and Weyl semimetals, semiconductors, heavy fermions, and new superconductors. She is a specialist in ARPES and synchrotron techniques.
