Super Conducting Hopping Mechanism and Flux Quantization on the Basis of Generalized Statistical Physical Model

Abstract

Super conductivity is one of the most important physic phenomenons that has a wide variety of applications in technology. It was successfully described by BCS theory. But recently some materials that act as a superconductor at higher temperatures, changes critical temperature due to the effect of pressure or isotope mass. This cannot be explained by BCS model. Some researchers suggest hoping mechanism for explaining high temperature super conductor’s behavior. But unfortunately the models proposed are complex and incomplete. The aim of this work is to use the generalized statistical physical model proposed by some researchers was used to explain the conditions that lead to hopping when kinetic energy exceeds coulomb potential, which agrees with that proposed by Hubbard model. The hopping also proved to take place below critical temperature, while it does not exist above this critical temperature. The hopping is also destroyed when magnetic field exceeds certain critical value. The flux is also quantized with in the frame work of this models. The results obtained by this model agree with observations and previous modelsThus one can conclude that generalized statistical model can successfully describe some superconducting phenomena
