A platform for nuclear symmetry-violation searches with laser-coolable molecules carrying spinful nuclei
Tatsam Garg, Jakob Weiß, Tesse Tiemens +3
Cold heavy molecules are promising systems for exploring nuclear - and -violating phenomena in search of new physics beyond the Standard Model. However,…
Numerical modeling of laser cooling in molecules: From simple diatomics to polyatomics and radioactive species
Felix Kogel, Tatsam Garg, Phillip Groß +9
Optical Bloch equations and rate equations serve as powerful tools to model light-matter interactions from textbook-like two-level atoms to the complex internal dynamics of molecul…
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…
Self-bound monolayer crystals of ultracold polar molecules
Matteo Ciardi, Kasper Rønning Pedersen, Tim Langen +1
We investigate the physics of ultracold dipolar molecules using path-integral quantum Monte Carlo simulations, and construct the complete phase diagram extending from weak to stron…
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…
