What is a Schiff moment anyway?

Atomic Physics 2026-02-10 v3 Nuclear Experiment

Abstract

Schiff moments of atomic nuclei are of considerable interest to experiments searching for undiscovered new physics that breaks time-reversal symmetry. I develop a simple picture of the Schiff moment of a charge distribution, and discuss the interaction of the Schiff moment of a nucleus with the field produced by an electron in an atom.
