Picosecond pulses test limits of dissipationless superconducting currents
Original: Picosecond current pulses probe intrinsic limit for dissipationless transport in superconductors
Researchers have used picosecond-duration current pulses to probe how fast and intense electrical currents can be in superconductors before the dissipationless state breaks down, testing an intrinsic limit of superconducting transport. The findings refine understanding of how superconductors carry current without resistance, with relevance for fundamental physics and future low-loss electronic technologies.
Why now: A newly published study in a major physics journal highlights a fundamental limit relevant to superconducting electronics research.
