Description
Dipolar molecules have been identified for many years as a platform to extend the achievements of ultracold atoms in quantum sensing, metrology and computing, but practical challenges have so far obstructed their feasibility. Recent advancements in experimental techniques over the last year have overcome many of the obstacles, culminating in the creation of the first molecular Bose-Einstein condensate earlier this year.
In recent work, we have explored the feasibility of Path Integral Monte Carlo applied to a realistic model of dipolar molecules. Sophisticated techniques such as PIMC are necessary to provide reliable simulation results, since mean-field approaches, routinely used for dilute and weakly-interacting ultracold gases, break down in the presence of stronger interactions. In this talk, I will present our findings on cluster formation for a model of dipolar molecules in quasi-1D geometry. I will discuss the advantages and limitations of current QMC approaches, and outlooks towards realizing a single-particle crystal with ultracold molecules.
