Lorentz Violation, CPT violation, and Spectroscopy Experiments

This presentation provides a brief overview of tests of Lorentz symmetry in atomic spectroscopy experiments, focusing on exotic atoms and models of Lorentz violation that include nonminimal effects. The talk discusses prevalent signals for Lorentz violation in atomic spectroscopy experiments, such as sidereal variation and CPT violation. It also highlights the importance of testing Lorentz symmetry using exotic atoms like muonium, antihydrogen, and muonic hydrogen. Finally, a brief discussion is provided on experiments used to constrain nonrelativistic coefficients for Lorentz violation, along with prospects for improving these bounds and imposing limits on unconstrained coefficients.
