A universal mechanism of superconductivity applicable to " low temperature " and " high temperature " superconductors is proposed in this paper. With this model of mechanism experimental facts of superconductors can be qualitatively explained. A function is introduced to describe the average separation distance between vibrating lattice atoms, which is crucial for the transition from normal to ...

The carbon neutrality goal of achieving net-zero by 2050 has sparked significant interest in offshore wind farms. With the farms installed > 100 km away from seashore, underground power transmission infrastructure is a necessity. Considering cable length and low net effective losses, high-voltage direct-current (HVDC) system chosen for this study. Also being lossless DC operation, HVDC cables a...
