Electrostatic Fields

The theory of electrostatic fields in superconductors at equilibrium is reviewed. We start from the simple Bernoulli potential balancing the Lorentz and inertial forces. Then we add interaction of superconducting and normal electrons and forces due to gradients of the condensation energy. Nonlocal relation between perturbing forces and the induced electrostatic field is formulated within the extended Ginzburg-Landau theory.

Favorable Conditions

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 favorable conditions to enhance the effect, optimizing the superconductor parameters characterizing the chosen sample. We also give a qualitative comparison of the behavior of high–Tc and classical low–Tc superconductors with respect to the gravity/superfluid interplay.

The Magnetic Field

A method which preserves the flux-quantization condition in all orders of perturbation theory is applied to the Ginzburg–Landau theory of type-II superconductors near the upper critical field. Expansions are obtained for the order parameter, the magnetic field, and the free energy; previous results are verified and extended to one higher order in Hc2 – Ha.
