The deformation of the superconductor crystal lattice caused by Abrikosov vortices is expressed as response of the elastic crystal lattice to electrostatic forces. It is shown that the lattice compression is linearly proportional to the electrostatic potential known as the Bernoulli potential, which is related to the kinetic energy of the supercurrents. Possible consequences of the crystal lattice deformation on the effective vortex mass are discussed. [cond-mat/0609669]
