Numerical modeling of laser cooling in molecules: From simple diatomics to polyatomics and radioactive species
Felix Kogel, Tatsam Garg, Phillip Groß +6
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…
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…
Isotopologue-selective laser cooling of molecules
Felix Kogel, Tatsam Garg, Marian Rockenhäuser +2
Direct laser cooling of molecules has made significant progress in recent years. However, the selective cooling and manipulation of molecules based on their isotopic composition, w…
Laser cooling of barium monofluoride molecules using synthesized optical spectra
Marian Rockenhäuser, Felix Kogel, Tatsam Garg +2
We demonstrate laser cooling of barium monofluoride (138BaF) molecules. We use serrodynes to synthesize time-sequenced optical spectra that can be precisely tailored to the hyperfi…
Absorption spectroscopy for laser cooling and high-fidelity detection of barium monofluoride molecules
Marian Rockenhäuser, Felix Kogel, Einius Pultinevicius +1
Currently, there is great interest in laser cooling of barium monofluoride (BaF) molecules for precision tests of fundamental symmetries. We use high-resolution absorption spectros…
A scalable scanning transfer cavity laser stabilization scheme based on the Red Pitaya STEMlab platform
Einius Pultinevicius, Marian Rockenhäuser, Felix Kogel +4
Many experiments in atomic and molecular physics require simultaneous frequency stabilization of multiple lasers. We present a stabilization scheme based on a scanning transfer cav…
A laser cooling scheme for precision measurements using barium monofluoride (137Ba19F) molecules
Felix Kogel, Marian Rockenhäuser, Ralf Albrecht +1
We theoretically investigate the laser cooling of fermionic barium monofluoride (137BaF) molecules, which are promising candidates for precision studies of weak parity violation an…
Realization of -symmetric and -symmetry broken states in static optical lattice potentials
Felix Kogel, Sebastian Kotzur, Daniel Dizdarevic +2
R. Labouvie et al. [Phys. Rev. Lett. 116, 235302 (2016)] have described an experiment with a weakly interacting Bose-Einstein condensate trapped in a one-dimensional optical lattic…
