Versatile objectives with NA = 055 and NA = 078 for cold-atom experiments

Electromagnet Design Basics for Cold Atom Experiments

Efficient continuous-duty Bitter-type electromagnets for cold atom experiments.

We present the design, construction, and characterization of Bitter-type electromagnets which can generate high magnetic fields under continuous operation with efficient heat removal for cold atom experiments. The electromagnets are constructed from a stack of alternating layers consisting of copper arcs and insulating polyester spacers. Efficient cooling of the copper is achieved via parallel ...

Fast machine-learning online optimization of ultra-cold-atom experiments

We apply an online optimization process based on machine learning to the production of Bose-Einstein condensates (BEC). BEC is typically created with an exponential evaporation ramp that is optimal for ergodic dynamics with two-body s-wave interactions and no other loss rates, but likely sub-optimal for real experiments. Through repeated machine-controlled scientific experimentation and observa...

Comparing the questions -proposed for this discourse panel with those identified for the TINLAP-2 panel eight years ago, it becomes clear that some progress has been made in discourse studies. While TINLAP-2's questions seem concerned with identifying an ideal model of discourse (e.g., what constitutes an appropriate model of discourse, how domain-dependent must such models be, what makes disco...
