Fundamental results on an Alkali-Alkaline earth-like dual-species optical tweezers for quantum simulation

We present an alkali (Rb) alkaline earth-like (Yb) dual-species optical tweezer array system for quantum simulation and quantum optics experiments. To efficiently and reliably align the pair of high numerical aperture objectives through which we project optical tweezers and image the atoms, we developed and implemented a novel optical interferometer which combines Twyman-Green and Fizeau interferometers. We describe the construction and alignment of this interferometer and how it enables the alignment of all relevant optical beams to a common focal plane where the atoms are trapped. We present preliminary data demonstrating the loading of Rb and Yb into optical tweezers and characterize the performance of the system in terms of trap depth and frequency, atomic loading fraction and temperature, and imaging fidelity and survival probability.
