For the first time, American researchers have succeeded in creating a so-called superconductor that works at room temperature. This technology has the potential to revolutionize how we use electricity, and save billions in energy efficiency improvements.

There is a direct connection to the American discovery and what a research group at the SCI school is working on. Oscar Tjernberg , Materials and Nanophysics, Department of Applied physics, leads a KAW project and a group that researches quantum materials and especially high-temperature superconductors. They have just moved from Kista to Albano and are building a new lab where the idea is that they will be able to create pressure waves in materials using short light pulses and then study how the electronic structure in the materials changes due to these pressure waves.
–Specifically, we will try to study how dynamic pressure affects superconductors with the hope of seeing how pressure changes the electronic structure and how it can induce superconductivity at high temperature. In other words, there is a direct link to the American discovery concerning that pressure can have a dramatic effect on the critical temperature and what we are work on, Oscar Tjernberg says.
