The transport properties of various systems are studied here in the context of three different models. These are: - the disordered Hubbard model applicable to correlated binary alloys with a general disorder. - the Anderson model used in describing the Kondo physics of a quantum dot connected to the external superconducting leads. and - the Ranninger-Robaszkiewicz model applied to the... https://oxfordshopes.shop/product-category/trousers-split-suit-auden/
