Mathematical Basis for Analyzing Superconducting Phase Transitions Using Catastrophe Theory
Jiu Hui Wu, Hua Tian, Kejiang Zhou
We establish a rigorous mathematical bridge from quantum many-body path integrals to the cusp catastrophe model by Lyapunov-Schmidt reduction, which provides a theoretical foundati…

Interfacial charge-induced adsorption mode for electron pairing in high-temperature superconductors
Jiu Hui Wu, Hua Tian, Kejiang Zhou
The electron pairing mechanism by the interfacial charge-induced adsorption mode of high-temperature superconductors is revealed. For the YBCO superconductors, the coupling of elec…

Thermodynamic adsorption potential of superconductors
Jiu Hui Wu, Jiamin Niu, Kejiang Zhou
Based on the general thermodynamic analysis of Polanyi adsorption potential, the adsorption potential condition for superconductors is obtained exactly by using the quantum state e…
