  • Mathews, Wesley Northey (1966)
    The Bogo1iubov equations are used to investigate the pair potential and the electronic excitations associated with a norma1- superconducting boundary in an extreme type I superconductor, The method of the Bogoliubov ...

  • Johnson, Jared Logan (1974)
    The change of normal current flow into supercurrent flow is examined in a number of problems in which the pair potential of the superconductor can vary spatially. We examine approximate solutions to the Bogoliubov equations ...

  • Clem, John Richard (1965)
    Various effects of anisotropy of the superconducting energy gap are theoretically considered. In order to estimate the effects of anisotropy upon the thermodynamic properties of pure, single-crystal superconductors, a ...

  • Simkin, David Alan (Department of Physics. College of Engineering. Graduate College. University of Illinois at Urbana-Champaign., 1963)
    Electrons in an alkali metal are allowed to interact by multiple processes, including direct coulomb interactions and retarded phonon exchanges, by including in the Hamiltonian both coulomb interaction and electron-phonon ...

  • Bray, James William (1974)
    This thesis examines theoretically the Fröhlich conductivity model, which describes a charge-density-wave phenomenon which can lead to enhanced electrical conductivity in pseudo-one-dimensional systems. The experimental ...

  • Ning, Tak Hung (Department of Physics. College of Engineering. Graduate College. University of Illinois at Urbana-Champaign., 1971)
    The pseudopotential theory of a substitutional impurity in a semiconductor is formulated using the orthogonalized-Bloch-wave method. A pseudo wave equation is obtained which is the same as the starting equation of the ...

  • Tefft, Wayne Earl (1964)
    A new technique for the calculation of electron scatter~ng in metals is proposed and developed. The method is considered valid both for crystals, at temperatures well above the Debye temperature, and for liquids, at ...

  • Swift, Jack Bernard (Department of Physics. College of Engineering. Graduate College. University of Illinois at Urbana-Champaign., 1968)
    Dynamic critical point phenomena in fluid systems are studied first by means of models and then with the aid of the scaling laws for critical exponents. Two models whose equilibrium distribution functions reduce to the ...
