We go beyond the approximate series expansions used in the dispersion theory of finite-size atoms. We demonstrate that a correct, and nonperturbative, theory dramatically alters the dispersion self… Expand

Accurate relativistic coupled-cluster studies with basis sets up to h-functions result in a static dipole polarizability of 9.11 au = 1.35 A3 for Rb+ . Relativistic effects are of the same size as… Expand

The role the exchange of phonons between pairs of fermions moving in time reversal states lying close to the Fermi energy on the superfluidity and on the superconductivity of atomic nuclei and… Expand

We calculate the optical-phonon correction to the binding energy of electrons to donors in cubic materials. Previous theories calculated the Rydberg energy reduced by the effective mass and the… Expand

In our previous work [P. Itskowitz and M. L. Berkowitz, J. Phys. Chem. A 101, 5687 (1997)], we showed how in the framework of the density functional theory the energy of a molecule can be expressed… Expand
