Impurity Effect on Kramer-Pesch Core Shrinkage in s-Wave Vortex and Chiral p-Wave Vortex
N. Hayashi, Y. Kato, M. Sigrist
The low-temperature shrinking of the vortex core (Kramer-Pesch effect) is studied for an isolated single vortex for chiral p-wave and s-wave superconducting phases. The effect of n…
Relation between Vortex Pinning Energy and Anderson's Theorem
Nobuhiko Hayashi, Yusuke Kato
We discuss the elementary vortex pinning in type-II superconductors in connection with the Anderson's theorem for nonmagnetic impurities. We address the following two issues. One i…
Interplay between Vorticity and Chirality inside the Vortex Core in Chiral p-Wave Superconductors
Nobuhiko Hayashi, Yusuke Kato
The vortex core in chiral p-wave superconductors exhibits various properties owing to the interplay between the vorticity and chirality inside the vortex core. In the chiral p-wave…
Critical Temperature Tc versus Charging Energy Ec in Molecular-Intercalated Fullerenes
Chikao Kawabata, Nobuhiko Hayashi, Fumihisa Ono
We study the recently discovered 117-Kelvin superconducting system C60/CHBr3 of the field-effect transistor and propose a possibility that the intercalation molecule CHBr3 plays a…
