TLDR
In this paper, a general form of the Ginzburgland-landau equations was derived for superconductor supercomputers, and the behavior of a high-Tc super-conductor with a classical low-tc superconducer was compared.Abstract:
We provide the detailed calculation of a general form for Maxwell and London equations that takes into account gravitational corrections in linear approximation. We determine the possible alteration of a static gravitational field in a superconductor making use of the time-dependent Ginzburg-Landau equations, providing also an analytic solution in the weak field condition. Finally, we compare the behavior of a high-Tc superconductor with a classical low-Tc superconductor, analyzing the values of the parameters that can enhance the reduction of the gravitational field.read more

Comments on gravitoelectromagnetism of Ummarino and Gallerati in “Superconductor in a weak static gravitational field” vs other versions
TL;DR: In this article, the Ummarino and Gallerati gravitoelectromagnetic equations in their linearized version of general relativity (GR) are shown to match with the previously reported special relativistic Maxwellian gravity equations in the non-relativistic limit and with the nonlinearized GR equations derived here, when the speed of gravity $$c_g$$ (an undetermined parameter of the theory here) is set equal to c (the speed of light in vacuum).

TL;DR: The transport coefficients in the self-consistent Hartree approximation are evaluated which interpolates smoothly between the high-tem temperature regime, dominated by Gaussian fluctuations, and the low-temperature flux-flow regime, with no intervening divergence.
