Screening and enhancement of oscillating electric field in molecules

H. B. Tran Tan, V. V. Flambaum, I. B. Samsonov

According to the Schiff theorem, the atomic electrons completely screen the atomic nucleus from an external static electric field. However, this is not the case if the field is tim…
