We study effects of strong fluctuations on the transport properties of superconductors near the classical critical point. In this regime conductivity is set by the delicate interplay of two competing effects. The first is that strong electron-electron interactions in the Cooper channel increase the lifetime of fluctuation Cooper pairs and thus enhance conductivity. On the other hand, quantum pair-breaking effects tend to suppress superconductivity. An interplay between these processes defines…

Temperature Dependence of the Anomalous Hall Effect from Electron Interactions.
The importance of electron interactions in the Cooper channel even for nominally non-superconducting materials is demonstrated and the corresponding low-temperature dependence of the anomalous Hall conductivity is found to be asymptotically of the form sqrt[T]/ln(T_{0}/T) in three dimensions and ln[ln( t)/T)] in two dimensions.
Anomalous mesoscopic kinetics in disordered superconductors
We study anomalous mesoscopic transport effects at the onset of superconducting transition focusing on the observed large Nernst-Ettinghausen signal in disordered thin films. In the vicinity of

Interaction corrections to tunneling conductance in ballistic superconductors
It is known that in the two-dimensional disordered superconductors electron-electron interactions in the Cooper channel lead to the negative logarithmical in temperature correction to the tunneling

The essential point of the calculations is that the electron phase-relaxation rate due to the electron-electron interaction in the Cooper channel is a singular function of the electron frequency.
Nonlinear fluctuation phenomena in the transport properties of superconductors
AbstractThere exists a wide temperature region $$(GiT < T - T_c < T\sqrt {Gi} )$$ where the influence of fluctuations on the thermodynamic properties of superconductors can be taken into account in

A new energy scale appears as a result of the quantum-fluctuation effects, which leads to a peculiar temperature and magnetic-field dependence of the tunneling conductivity close to the transition.

We derive Ginzburg-Landau action by systematically integrating out electronic degrees of freedom in the framework of the Keldysh nonlinear $\ensuremath{\sigma}$-model of disordered superconductors.
