Experimental Probes of Superconductivity: Advances and Challenges

Superconductivity remains one of the most intriguing frontiers in condensed matter physics. Despite major breakthroughs, fully understanding its underlying mechanisms continues to challenge the field. Experimental methods such as angle-resolved photoemission spectroscopy (ARPES), resonant inelastic X-ray scattering (RIXS), neutron scattering, and X-ray diffraction have been vital in probing the relationships between lattice, spin, and electronic properties. Yet, even with state-of-the-art instrumentation, key questions persist about how these interactions drive superconductivity and how different experimental results can be unified into a coherent picture.Challenges remain in combining insights across methods, establishing common analysis standards, and producing reproducible datasets that bridge experiment and theory. With the discovery of new superconductors, from high-pressure hydrides to low-dimensional and topological systems, collaboration across experimental disciplines is more important than ever.This Research Topic aims to highlight advances and challenges in experimental probes of superconductivity, showcasing the tools and innovations that are shaping our understanding of superconducting materials and phenomena. We welcome studies that introduce new techniques, integrate complementary methods, or link experimental results to theoretical models.Topics include but are not limited to:- Experimental probes such as ARPES, RIXS, neutron scattering, and diffraction methods- Methodological innovations in data analysis, reproducibility, and cross-validation- Case studies of unconventional or emerging superconductor Topic editors: Alexei Fedorov Source: https://www.frontiersin.org/research-topics/83120/experimental-probes-of-superconductivity-advances-and-challenges
