(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 ...

(Department of Physics. College of Engineering. Graduate College. University of Illinois at UrbanaChampaign., 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 electronphonon ...

(Department of Physics. College of Engineering. Graduate College. University of Illinois at UrbanaChampaign., 1971)The pseudopotential theory of a substitutional impurity in a semiconductor is formulated using the orthogonalizedBlochwave method. A pseudo wave equation is obtained which is the same as the starting equation of the ...

(Department of Physics. College of Engineering. Graduate College. University of Illinois at UrbanaChampaign., 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 ...
