First-Principles Quantum-Spectral framework for Elementary Vortex Pinning in superconductors
Haozhe Shi, Yuncheng Xie, Tong Zhang +2
The critical current of a type-II superconductor is controlled by vortex pinning, whose microscopic input is the elementary pinning force. Scanning tunneling spectroscopy has shown…
