Two-dimensional fluctuation-induced conductivity above the critical temperature

A microscopic calculation of the fluctuation-induced conductivity above the transition temperature is formulated in the two-dimensional case including magnetic field effects and isotropic impurity scattering. The fluctuation conductivity is found to depend on magnetic field and temperature through a dimensionless parameter $\gamma =\frac{2\epsilon \mathrm{kT}}{\pi \mathrm{DeH}}$.
