Influence of Quantized Vortex Dynamics on Superconducting Electronics

Explore the impact of quantized vortex dynamics on superconducting electronics in this 48-minute HyperComplex Seminar talk. Delve into the world of superconducting materials and their quantum phenomena on a macroscopic scale, focusing on quantized vortices transporting magnetic flux. Examine how pancake-type vortices in HTc multilayered superconductors affect current-voltage characteristics and critical current density during the flux creep process. Learn about the importance of these parameters in superconducting electronic quantum devices and power apparatus. Review the author's work on superconducting cables and investigate how various initial states and shapes of captured vortices influence pinning potential barriers. Discover how fitting current-voltage characteristics to experimental data helps determine material parameters of HTc superconductors, such as nano-sized defect concentration. Analyze critical current density as a function of irradiation dose and magnetic induction, exploring the initial enhancement and subsequent decrease due to lattice destruction. Apply vortex dynamics analysis to interpret dynamic anomalies in current-voltage characteristics and describe irradiation from long Josephson's junctions. Conclude with a discussion on superconducting semiconductors with lanthanum vacancies and their potential applications in joined superconducting-semiconducting electronic quantum devices.
