Genuine Molecular Effects in Bound-State Quantum Electrodynamics

Kjell Janke, Konstantin Gaul, I. Agustín Aucar +5

Quantum electrodynamics (QED) currently features prominently at the precision frontier in describing the structure of atoms and molecules. Dominant QED effects are governed by the…

Prospects for measuring the electron's electric dipole moment with polyatomic molecules in an optical lattice

Roman Bause, Nithesh Balasubramanian, Ties Fikkers +8

We present the conceptual design of an experiment to measure the electron's electric dipole moment (eEDM) using BaOH molecules in an optical lattice. The BaOH molecule is l…

Parity-violating nuclear spin-rotation and NMR shielding tensors in tetrahedral molecules

Ignacio Agustín Aucar, Yuly Andrea Chamorro Mena, Anastasia Borschevsky

In natural processes involving weak interactions, a violation of spatial parity conservation should appear. Its effects are expected to be observable in molecules using different s…
