Two Dimensional Phenomena in High Temperature Superconductors,ors suggests the presence of two-dimensional (2D) superconductivity. It is shown here that an array of 2D Josephson junctions can account for this behavior. The junctions exhibit an additional phase transition above which the layers are uncorrelated. The sesitivity of the latter transition to magnet

These oscillations require an Einstein spectrum, or at least small dispersion. The oscillatory solutions are insensitive to the Coulomb repulsion μ. They are obtained from the Dyson

Coherent Back Scattering and Other Optical Effects in Random Media,iscussed and a scaling theory is presented. Results on the fluctuations and correlations in the transmitted light are presented. The effects of inelastic scattering arising from particle motion on the spectral distribution of the scattered light is discussed. It is pointed out that there is an inter

The scattered waves interfere with each other and, as a result, a certain intensity pattern (a speckle pattern) is formed within the sample. This speckle pattern is highly irregular, with large intensity variations over short distances. The irregularities are not due
