A New Approach to the Josephson Effect
Yong-Jihn Kim
We introduce a new approach to the Josephson effect in SIS tunnel junctions. The Josephson coupling energy is calculated from the overlap of real space Cooper pair wavefunctions in…
Different Behavior of Magnetic Impurities in Crystalline and Ammorphous States of Superconductors
Mi-Ae Park, Kerim Savran, Yong-Jihn Kim
It has been observed that the effect of magnetic impurities in a superconductor is drastically different depending on whether the host superconductor is in a crystalline or an amor…
Weak localization and the Mooij rule in disordered metals
Mi-Ae Park, Kerim Savran, Yong-Jihn Kim
Weak localization leads to the same correction to both the conductivity and the McMillan's electron-phonon coupling constant (and ). Consequently the temperature depend…

On the Mooij Rule
Mi-Ae Park, Kerim Savran, Yong-Jihn Kim
Weak localization leads to the same correction to both the conductivity and the electron-phonon coupling constant (and ). Consequently the temperature dependence of the…
Absence of the Vortex Solution in Gor'kov's Formalism
Yong-Jihn Kim
It is shown that the Abrikosov's vortex solution or its corresponding two-particle pair potential is not the solution of the self-consistency equation in Gor'kov's formalism. Since…
