Non-Perturbative Theory for Dispersion Self-Energy of Atoms
Priyadarshini Thiyam, C. Persson, I. Brevik +2
We go beyond the approximate series-expansions used in the dispersion theory of finite size atoms. We demonstrate that a correct, and non-perturbative, theory dramatically alters t…

Finite size dependent dispersion potentials between atoms and ions dissolved in water
P. Thiyam, M. Boström, C. Persson +3
A non-expanded theory is used for dispersion potentials between atoms and ions dissolved in a medium. The first-order dispersion interaction between two atoms in an excited state m…
