Angle-Resolved Photoemission Spectroscopy (ARPES) is a powerful tool used to study the momentum dependent electronic structure of solids, elucidating the connection between electronic, magnetic, and chemical structure. The availability of dedicated ARPES beamlines in state-of-the-art synchrotron facilities – such as the recently completed Quantum Materials Spectroscopy Centre (QMSC) at the Canadian Light Source (CLS) – is essential to achieving a deeper understanding of new phases of matter in quantum materials, and their application potential for future technologies.

The Workshop QMSC at CLS: New Developments in Fe-based Superconductivity, co-organized by the Canadian Light Source Inc. and the Stewart Blusson Quantum Matter Institute, will be held virtually on  December 13 and 14, 2021. The aim of this workshop is twofold.

First, this workshop will provide an overview of the QMSC at CLS, a beamline facility dedicated to performing spin- and angle-resolved photoemission spectroscopy (Spin+ARPES), operating with circular and linear polarization in the 15-1200 eV photon energy range. Commissioning results will be presented for the ARPES branch, together with an overview of the upcoming Spin+ARPES branch.

Second, to further showcase QMSC’s capabilities and more generally the power of Spin+ARPES in the investigation of quantum materials, we will discuss a number of case studies performed on Fe-based superconductors in both thin-film and single crystalline form. This work addresses the dimensionality and orbital character of the low-energy electronic structure, symmetry breaking instabilities, interfacial superconductivity and electron-phonon coupling, as well as magnetic moment fluctuations.

Looking forward to an exciting event and meeting you all at QMSC at CLS!
