Swedish-Ukranian workshop on science and technology of superconductivity

26 Oct 2026, 08:30 → 27 Oct 2026, 18:00 Europe/Stockholm

Häggsallen (Ångström Laboratory)

Mats Larsson (Stockholm University), Vitaliy Goryashko (Uppsala University)

Scope:

Superconducting (SC) and low-temperature quantum systems are transforming our understanding of matter, energy, and information. SC technologies are part of the transition to a green society through energy saving in high-power applications as, for example, SC accelerators and high-Tc SC power lines. The Swedish-Ukrainian symposium provides a platform for discussing novel and emergent phenomena in the applied science and technology of superconductivity, in particular for applications in future accelerators. 

Chairs:

• Vitaliy Goryashko (Uppsala University,  Sweden)
• Mats Larsson (Stockholm University, Sweden)
• Larissa Brizhik (Bogolyubov Institute for Theoretical Physics, Ukraine)
