Different Electronic Charges in Two-Component Superconductor by Coherent State
arXiv:1607.03994 · doi:10.1016/j.physleta.2015.03.012
Abstract
Recently, the different electronic charges, which are related to the different coupling constants with magnetic field, in the two-component superconductor have been studied in frame of Ginzburg-Landau theory. In order to study the electronic charges in detail we suggest the wave function in the two-component superconductor to be coherent state. We find the different electronic charges exist not only in the coherent state but the incoherent state. But the ratio of the different charges in the coherent state is different from ratio in the incoherence. The expressions of the coupling constants are given directly based on the coherence effects. We also discuss the winding number in such system.
