Prospects for testing Lorentz symmetry with highly charged ions
Arnaldo J. Vargas
We investigate the prospects for testing Lorentz symmetry using highly charged ions. We derive the Lorentz-violating energy shifts relevant to Zeeman and Zeeman-hyperfine transitio…
Nonminimal Lorentz Violation in Atomic and Molecular Spectroscopy Experiments
Arnaldo J. Vargas
This presentation discusses potential signals of Lorentz violation that could be observed in atomic and molecular spectroscopy experiments. It provides a general overview of the no…
Prospects for testing Lorentz and CPT symmetry with and
Arnaldo J. Vargas
This work presents a model for testing Lorentz and CPT symmetry using rovibrational transitions within the electronic ground state of the molecular hydrogen ion (H). The mode…
Muonium fine structure: theory update, tests of Lorentz violation and experimental prospects
Philipp Blumer, Svenja Geissmann, Arnaldo J. Vargas +3
We review the status of the QED calculations for the muonium energy interval and provide the updated theoretical value of . Addi…
Prospects for testing CPT and Lorentz symmetry with deuterium ground-state Zeeman-hyperfine transitions
Arnaldo J. Vargas
This work presents a model for testing Lorentz and CPT symmetry through sidereal-variation studies of the hyperfine-Zeeman deuterium ground-state transition frequencies. It represe…
Lorentz- and CPT-violating effects in Penning traps at linear boost
Ariam J. Acevedo-Lopez, Yunhua Ding, Kaito Iwasaki +1
We present in this work an analysis of Lorentz- and CPT-violating signals at linear boost order in Penning-trap experiments. The theory of quantum electrodynamics with Penning trap…
Lorentz Violation, CPT violation, and Spectroscopy Experiments
Arnaldo J. Vargas
This presentation discusses some of the signals for Lorentz violation potentially observable in atomic spectroscopy and clock-comparison experiments. The emphasis of the discussion…
Lorentz and CPT Tests with Clock-Comparison Experiments
Alan Kostelecky, Arnaldo J. Vargas
Clock-comparison experiments are among the sharpest existing tests of Lorentz symmetry in matter. We characterize signals in these experiments arising from modifications to electro…
Signals for Lorentz and CPT Violation in Atomic Spectroscopy Experiments and Other Systems
Arnaldo J. Vargas
The prospects of studying nonminimal operators for Lorentz violation using spectroscopy experiments with light atoms and muon spin-precession experiments are presented. Possible im…
Lorentz and CPT tests with hydrogen, antihydrogen, and related systems
Alan Kostelecky, Arnaldo J. Vargas
The potential of precision spectroscopy as a tool in systematic searches for effects of Lorentz and CPT violation is investigated. Systems considered include hydrogen, antihydrogen…
Laboratory tests of Lorentz and CPT symmetry with muons
Andre H. Gomes, Alan Kostelecky, Arnaldo J. Vargas
The prospects are explored for testing Lorentz and CPT symmetry in the muon sector via the spectroscopy of muonium and various muonic atoms, and via measurements of the anomalous m…
