Harvard University Team Probes Vortex Dynamics for Understanding Superconducting Levitation

Quantum ZeitgeistJuly 13, 20266 min read

Previously, magnetically levitated particles suffered mechanical quality factors limited to 107. Now, observations of random telegraph signals within a levitated particle reveal the dynamics of individual vortices in a YBCO superconducting film. This offers a new way to explore dissipation mechanisms and potentially create highly sensitive mechanical transducers.

Scientists are developing innovative techniques to investigate the behaviour of vortices within high-temperature superconductors, a crucial step towards optimising materials for applications such as magnetic levitation and lossless energy transmission. Yiqi Wang at Harvard University and colleagues have pioneered a method employing the mechanical motion of micron-scale levitated magnetic particles to probe the dynamics of individual vortices trapped within a YBCO superconducting film. Their observations of random telegraph signals and non-exponential decay in the particles' behaviour provide valuable insights into vortex-defect interactions and the underlying potential landscapes governing these phenomena, offering a pathway to enhance the performance of superconducting levitated systems and utilise…
