The workshop ”Superconducting Hybrids @ Extreme” organized in the framework of the COST action CA16218 will be focused on recent advances in superconducting coherent hybrid structures at extreme experimental conditions of ultralow temperatures, high magnetic fields, high pressures and at nanoscale. It aims at boosting discussions on superconducting nanostructures and materials, nanoscale devices, hybrids made of superconducting and magnetic systems, topological materials, superfluids and strongly correlated electron systems addressed by different kinds of techniques from nanoprobes to transport, thermodynamic and magnetic measurements. Theoretical works on the topics are welcome, too. Stimulating discussions between experiment, theory and computational approaches are expected. [More information]
