Query: Bulk-mediated interaction between impurities in 1D atomic chains   A combination of numerical and analytical methods is employed to study a
one-dimensional chain of identical atoms with adsorbates. We show that the
electron-mediated interaction energy between two impurities can change sign and
magnitude depending on the adatom-adatom separation, as well as the system
doping. By focusing on this simple system, we provide insight into the
bulk-mediated interaction for more complex materials.
