Trapped Laser-cooled Molecules for Quantum Simulation, Particle Physics, and Collisions — •John Doyle — Harvard University, Cambridge, USA
Due to the controllable complexity of cold polar molecules - in particular the body frame fixed electric dipole of polar molecules - they are a potentially powerful platform for quantum simulation. This has led to significant efforts to control molecules at the quantum level. We report on laser cooling and trapping of molecules and the creation of optical tweezer arrays of ultracold CaF molecules in a single quantum state. We have also conducted collision studies using optical tweezers, demonstrating the potential for exploring state-selective ultra-cold quantum chemistry on a molecule by molecule basis. These methods can be extended beyond diatomic molecules to polyatomic molecules, which have additional features that are advantageous for quantum computation and particle physics. For example, we have advanced a scheme for quantum computation using symmetric top molecules in optical tweezers. We will also discuss progress toward laser cooling of polyatomic molecules such as CaOH, YbOH, CaSH, and YbOCH3, and their potential use in experiments, including precision searches for new particles (beyond the standard model) and quantum information.
