Description
Molecules are emerging as powerful platforms for precision measurement science, offering unique sensitivity for high-resolution spectroscopy and tests of fundamental symmetries. These experiments probe energy scales and interactions that complement searches at high-energy collider facilities, opening new avenues for discovering physics beyond the Standard Model in previously unexplored regimes.
However, although established techniques exist for controlling molecular vibrational and rotational degrees of freedom, laser cooling remains challenging for heavy species with complex hyperfine structure arising from multiple nuclear spins. These species are especially relevant in searches for nuclear parity (P) and time-reversal (T) violation.
In this talk, I will introduce novel laser-cooling strategies designed to address these challenges. I will present experimental demonstrations of these techniques applied to several isotopologues of barium monofluoride and discuss their scalability and prospects for cooling other molecular species - including radioactive ones - relevant to precision tests of fundamental symmetries.
