Description

Quantum materials are a broad class of solids whose properties emerge from quantum-mechanical and collective electronic effects that have no classical counterpart, superconductivity being one of the best-known examples. Non-trivial band topology gives rise to further exotic phenomena, such as robust spin-polarized surface states, making these materials highly attractive for spintronics and quantum computing. Angle-resolved photoemission spectroscopy (ARPES) is ideally suited to studying these systems, as it directly maps their electronic band structure. Synchrotron radiation adds key advantages. Tuneable photon energy gives access to the three-dimensional band structure (especially relevant for Co-based shandites covered in this talk) and helps separate surface states from bulk bands, while variable light polarization reveals the orbital character of individual bands. Resolving this complex, multiband electronic structure is key both to understanding quantum materials and to designing new ones with tailored properties. This talk will present ARPES studies of several different topological materials, including recent beamtime results at the SOLARIS synchrotron.
