The critical current is a crucial figure of merit for applications, and materials science has long been focused on increasing this limit. Researchers at the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) have now shown that, in type-II superconductors, this conventional limit can be exceeded when the current is applied for only a few picoseconds.<\/p>\n<p>On these ultrashort timescales, the researchers were able to access a much higher, intrinsic limit known as the depairing current. The work has now been <a href=\"https:\/\/www.nature.com\/articles\/s41567-026-03469-z\" target=\"_blank\">published<\/a> in Nature Physics.<\/p>\n<p>Superconductivity is one of the most striking collective phenomena in quantum materials. When certain materials are cooled below a characteristic transition temperature, their electrical resistance vanishes, and electric current can flow without dissipating energy as heat. This unusual behavior arises because electrons form correlated pairs, known as <a href=\"https:\/\/phys.org\/news\/2022-06-atomic-scale-window-superconductivity-paves-quantum.html?utm_source=embeddings&utm_medium=related&utm_campaign=internal\" rel=\"related\">Cooper pairs<\/a>, which move collectively through the material like a wave. Superconductors are therefore attractive for technologies ranging from powerful magnets and sensitive detectors to quantum circuits.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Superconductors can carry electrical current without resistance, but only up to a maximum value known as the critical current.
