摘要

The interaction of the superconducting condensate with deformations of the crystal lattice is formulated assuming the electrostatic potential to be of Bernoulli type and the effect of strain on material parameters. In the isotropic approximation it is shown that within the Ginzburg-Landau theory both contributions can be recast into the local but nonlinear interaction term of the free energy.
