ELECTROSTATIC FIELD IN SUPERCONDUCTORSAT EQUILIBRIUM

摘要

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-Landan theory.
