Theoretical investigation of laser cooling in fermionic barium monofluoride ((BaF)-Ba-137) molecules has demonstrated the feasibility of optical cycling, sub-Doppler cooling, and bichromatic forces under realistically achievable experimental conditions.
We theoretically investigate the laser cooling of fermionic barium monofluoride ((BaF)-Ba-137) molecules, which are promising candidates for precision studies of weak parity violation and nuclear anapole moments. This molecular species features two nuclear spins, resulting in a hyperfine structure that is considerably more complicated than the one found in the usual laser-cooled diatomics. We use optical Bloch equations and rate equations to show that optical cycling, sub-Doppler cooling and bichromatic forces can all be realized under realistically achievable experimental conditions.
