| dc.description.abstractEn | The critical fluctuations in a mesoscopic superconducting ring are studied within the Ginzburg-Landau approach. The nonlocal conductivity as well as the specific heat are calculated as functions of the magnetic flux $\Phi$ through the ring. At $\Phi=\Phi_0/2$ two low-energy eigenstates become degenerate and near this point the behavior of fluctuations-dependent quantities change dramatically: both the zero Fourier component $\sigma_0$ of the fluctuation conductivity and the specific heat become non-monotonic functions of $|\Phi-\Phi_0/2|$ with rather special resonant structure. | |
