WitrynaImpurity-induced localization in cuprate superconductors - NASA/ADS The localization in a disordered metal by means of the perturbation approach is considered. It is shown that in the case of a given impurity potential a small disorder leads to localization in 2D as well as in 1D and causes the weak localization in 3D.
We consider impurities in the simplest 1D Hatano–Nelson chain43, which already exhibits nearly the full scope of impurity-induced phenomena in more generic lattices. An impurity is represented as a modified coupling between the first and last sites: with μ± = μe±α, μ controlling the local impurity, α > 0 and x = … Zobacz więcej To understand why SFA occurs, we analytically solve for the eigenstates \({{{\Psi }}}_{n}=\mathop{\sum }\nolimits_{x}^{L}{\psi }_{x,n}{\hat{c}}_{x}^{\dagger … Zobacz więcej The discussions above imply a duality between PBCs at μ = 1 and quasi-PBCs at μ = e2α.
