High-resolution spectroscopy of barium monofluoride: Odd isotopologues, hyperfine structure and isotope shifts
Felix Kogel, Yuly Chamorro, Mangesh Bhattarai +5
Barium monofluoride (BaF) is a promising molecular species for precision tests of fundamental symmetries and interactions. We present a combined theoretical and experimental study…
Magnetic hyperfine structure constants of BaF in the and excited states
Yuly Chamorro, Felix Kogel, Tim Langen +1
High-precision molecular experiments testing the Standard Model of particle physics require an accurate understanding of the molecular structure at the hyperfine level, both for th…
Laser cooled 137BaF molecules for measuring nuclear-spin-dependent parity violation
Felix Kogel, Tatsam Garg, Marian Rockenhäuser +1
We demonstrate optical cycling and transverse laser cooling of a beam of fermionic 137BaF molecules. Their high masses and nuclear spins make these molecules sensitive probes for p…
Molecular laser cooling using serrodynes: Implementation, characterization and prospects
Felix Kogel, Tatsam Garg, Marian Rockenhäuser +2
An important effort is currently underway to extend optical cycling and laser cooling to more molecular species. Significant challenges arise in particular when multiple nuclear sp…
