• Time-dependent Ginzburg-Landau
• Ac conductivity
• Type-II superconductor

We use the time-dependent Ginzburg-Landau to calculate ac fluctuation conductivity and resistivity in type-II superconductor in 3D model under magnetic field. Thermal fluctuations are assumed to be strong enough to melt the Abrikosov vortex lattice created by the magnetic field into a vibrating vortex liquid and marginalize the effects of the vortex pinning by inhomogeneities. The nonlinear interaction term in the time-dependent Ginzburg-Landau is treated within self-consistent Gaussian approximation. We obtain expressions the complex conductivity and resistivity summing all Landau
