Parity violation in two-photon J=0-to-1 transitions: Analysis of systematic errors

TL;DR

This paper analyzes potential systematic errors in measuring atomic parity violation via two-photon J=0-to-1 transitions, focusing on field misalignments and stray fields, and proposes methods to discriminate true signals from errors.

Contribution

It provides a detailed analysis of systematic uncertainties and strategies to mitigate them in atomic parity violation experiments using two-photon transitions.

Findings

Misalignment of fields can introduce significant errors.

Field reversals help distinguish parity-violating signals from systematic effects.

Zeeman structure analysis aids in identifying true parity violation signals.

Abstract

We present an analysis of systematic sources of uncertainty in a recently proposed scheme for measurement of nuclear-spin-dependent atomic parity violation using two-photon J=0-to-1 transitions driven by collinear photons of the same frequency in the presence of a static magnetic field. Two important sources of uncertainty are considered: misalignment of applied fields, and stray electric and magnetic fields. The parity-violating signal can be discriminated from systematic effects using a combination of field reversals and analysis of the Zeeman structure of the transition.
