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.

Josephson's effect in the Schwarzschild background
hep-th 2025-10 conditional novelty 5.0

Josephson dynamics in Schwarzschild spacetime reduce to flat-space laws with redshifted voltages, giving critical currents that scale as α, power as α², and Shapiro steps fixed in asymptotic variables.
