Lorentz Violation, CPT violation, and Spectroscopy Experiments

TL;DR

This paper explores how atomic spectroscopy and clock experiments can detect Lorentz and CPT violations, focusing on how quantum numbers influence observable sidereal variations in transition frequencies.

Contribution

It provides a detailed analysis of how angular-momentum quantum numbers affect the signals of Lorentz and CPT violation in spectroscopy experiments.

Findings

Quantum numbers determine sidereal variation patterns.

Spectroscopy can serve as a test for fundamental symmetry violations.

Analysis guides experimental searches for Lorentz and CPT violation.

Abstract

This presentation discusses some of the signals for Lorentz violation potentially observable in atomic spectroscopy and clock-comparison experiments. The emphasis of the discussion is on how the angular-momentum quantum numbers of the states involved in the transition determine the properties of the possible sidereal variation of the transition frequency.
