Quasi-1d Collisions of ⁸⁷Rb₂ molecules — •Björn Drews, Markus Deiss, and Johannes Hecker Denschlag — Institut of Quantum Matter

We observe Rubidium molecules in the Feshbach and ³Σ_u (v=0) state, colliding in a strongly anisotropic, quasi-1d potential. All interactions take place in an optical lattice in the ultracold regime. The filling in each 1d trap is on average only 3-4 molecules over a length of about 80 µm. This leads to complex dynamics in the time evolution of the system. A simple, intuitive model is devised to simulate this behavior and to extract the corresponding decay coefficients.
