Towards Laser Cooling of Radium Containing Molecules

ORAL · Invited

Abstract

Molecules incorporating heavy, octupole-deformed, radioactive nuclei such as radium offer enhanced sensitivity to yet-undiscovered parity- and time-reversal-violating nuclear properties. The violation of these symmetries is essential for understanding the matter-antimatter asymmetry in the universe and may reveal the existence of new fundamental particles. However, these radioactive molecules can only be produced artificially and in limited quantities, posing significant experimental challenges. This talk will present recent laser spectroscopy experiments on radium-containing molecules and progress towards their deceleration, trapping, and laser cooling.
