Sažetak
We analyze a model of electron lattice between two metallic or polar dielectric slabs. Typically, the electrons are confined on a thin helium layer above a metallic slab and form, under given circumstances, the Wigner lattice. We assume that another slab is placed above the electron layer at a distance away to have negligible influence on basic properties of the Wigner lattice. Here we want to analyze the total force acting on the lattice electrons as well as the total force acting between the metallic (or dielectric) slabs. From the classical electrodynamics one can determine the image potential and calculate corresponding forces. In the quantum electrodynamics, fluctuations of the electromagnetic field will add in attraction between the slabs due to the Casimir effect. We calculate and compare those two forces on the slabs within the same model, since they are an explicit manifestation of the same field. We found out that the resulting forces can be of comparable strengths in the appropriate setup.
