Introduction
The mechanism of high-temperature superconductivity in cuprates remains one of the most profound challenges in condensed matter physics. Decades of research have yielded numerous anomalous phenomena, yet a definitive theory, akin to BCS for conventional superconductors, remains elusive. Key mysteries persist, such as the starkly different critical temperatures between electron- and hole-doped cuprates, which challenge the sufficiency of antiferromagnetic fluctuations for pairing. Furthermore, the anomalous "normal state" — exhibiting non-Fermi liquid behavior like linear-in-temperature resistivity — suggests that superconductivity emerges from a fundamentally enigmatic quantum phase.
The recent discovery of high-Tc superconductivity in infinite-layer and bilayer nickelates, which share key structural features with cuprates, has opened a new chapter in the field. These materials provide a long-awaited comparative platform to test and refine theoretical models originally developed for cuprates.
This mini-workshop will convene leading experts in high-temperature superconductivity and strongly correlated electron systems. Our goal is to foster a dynamic exchange of recent theoretical and experimental insights, with the ultimate aim of unraveling the fundamental mechanisms of high-Tc superconductivity and paving the way for its realization at ever higher, and potentially room temperatures.
