Possible alterations of local gravitational field inside a superconductor

Abstract

We calculate the possible interaction between a superconductor and the static Earth's gravitational fields, making use of the gravito-Maxwell formalism combined with the time-dependent Ginzburg-Landau theory. We try to estimate which are the most favourable conditions to enhance the effect, optimizing the superconductor parameters characterizing the chosen sample. We also give a qualitative comparison of the behaviour of high-$T_{\text{c}}$ and classical low-$T_{\text{c}}$ superconductors with respect to the gravity/superfluid interplay.
