Brief description of research interests

We are interested in learning about the microscopic mechanisms that lead to the occurrence of collective effects in solids such as superconductivity and ferromagnetism. We believe that the essential physics of these phenomena is likely to be contained in simple models, even if the materials where these phenomena occur are very complicated. Once a plausible model is identified, we study it using various analytic and/or numerical techniques to learn about its properties and compare with experimental observations. For example we have recently introduced a new class of model Hamiltonians, 'dynamic Hubbard models' , to describe correlated electrons in solids. We have discovered that holes are not like electrons and that superconductivity in solids is intimately tied to the fundamental asymmetry between electrons and holes, because it originates in the undressing of antibonding electrons upon pairing , and are studying the consequences of this for optical, tunneling, and other experiments. We have recently found that the conventional BCS-London theory of superconductivity cannot explain the ubiquitous Meissner effect in superconductors. These findings imply that BCS theory is incorrect and that London theory is incorrect and that a superconductor is a giant atom. We have also proposed a new way to understand metallic ferromagnetism in solids, and that superconductivity and ferromagnetism have key physics in common. We are interested in kinetic energy driven superconductivity and superfluidity , and in the physics of spin currents in metals, superconductors, and molecules. We have proposed that the conventional 'Hall effect', the transverse voltage that is observed when a current circulates in an external magnetic field, should have as counterpart a 'spin Hall effect', involving the electron spin degrees of freedom. Similarly, we have proposed that the conventional Meissner effect, the spontaneous generation of a charge current near the surface of a superconductor in the presence of an external magnetic field, has as counterpart (so far undetected) a 'spin Meissner effect', the spontaneous generation of a spin current near the surface of a superconductor in the presence of an internal electric field.
