A.I. Larkin, Yu.N. Ovchinnikov
TL;DR
This paper investigates the low energy excitation spectrum of layered superclean superconductors with impurities, revealing correlated energy levels that significantly enhance conductivity at low temperatures.
Contribution
It introduces a detailed analysis of impurity effects on vortex excitations, highlighting the correlation of energy levels and their impact on conductivity enhancement.
Findings
Energy levels are correlated in vortex cores.
Impurities lead to enhanced conductivity in superclean layered superconductors.
Low temperature excitation spectrum is characterized by these correlations.
Abstract
The low energy excitation spectrum is found for a layered superconductor vortex with a small number of impurities inside the vortex core. All levels are found to be correlated. This leads to the strong enhancement of conductivity in superclean layered superconductors.
