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 $H_{2}^{+}$ and $H ˉ_{2}^{-}$

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 $_{2}^{+}$ ). 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 $2 S_{1/2} - 2 P_{3/2}$ energy interval and provide the updated theoretical value of $9874.357 \pm 0.001 MHz$ . Addi…
