Bridging Superconductors with UN Development Goals: Perspectives and Applications
Edimar A. S. Duran, Alfonso Pulgar, Rodolfo Izquierdo +4
Superconductors exhibit remarkable properties such as zero resistivity and diamagnetism at the boiling temperature of liquid hydrogen (20 K) and even aboven the boiling temperature…
Comparing energy dissipation mechanisms within the vortex dynamics of gap and gapless nano-sized superconductors
E. C. S. Duarte, E. Sardella, T. T. Saraiva +2
The presence of magnetic fields and/or transport currents can cause penetration of vortices in superconductors. Their motion leads to dissipation and resistive state arises, which…
