Microscopic Study of Quantum Vortex-Glass Transition Field in Two-Dimensional Superconductors
arXiv:cond-mat/0110361 · doi:10.1143/JPSJ.71.245
Abstract
The position of a field-tuned superconductor-insulator quantum transition occuring in disordered thin films is examined within the mean field approximation. Our calculation shows that the microscopic disorder-induced reduction of the quantum transition point found experimentally cannot be explained if the interplay between the disorder and an electron-electron repulsive interaction is ignored. This work is presented as a microscopic basis of an explanation (cond-mat/0105122) of resistive phenomena near the transition field.
