Abstract
We discuss the effect of an external electric field on the wetting of a solid surface by liquid. To this end, we use a model of the two-level-atom fluid for which the changes in interatomic interactions due to the presence of the field can be found using quantum-mechanical perturbation theory. Constructing the grand potential functional, we perform the standard calculations of Young's equilibrium contact angle. The switching on of the electric field may increase noticeably the contact angle .
