Fluctuation conductivity from charge density waves in pseudo-one-dimensional systems
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 facts concerning pseudo-one-dimensional systems which may illustrate aspects of …

Fluctuation contributions to the heat capacity of superconducting thin films
… superconductors. The presence of thermodynamic fluctuations causes a breakdown of mean field theory if one gets close enough to the transition temperature, T. For a pure bulk superconductor, the temperature region over which thermodynamic fluctuations become important is inuneasurably small. For …

Insulator-Superconductor Transitions in Two Dimensions
… the description near the IST, we consider the fluctuation conductivity near the quantum critical point (QCP) in the presence of dissipation. We show that sufficiently close to the QCP, Ohmic dissipation can change the dynamical critical exponent from z = 1 to z = 2 in the quantum critical (QC) …
