An extensive revamp of our setup has enabled the study of 2D physics using ultracold atoms. The details of the setup are published here:

We can let atoms expand in arbitrary potentials, such as a cavity shaped as a kiwi, a cat or a smiley face as shown here. Note that the entire size of the image is about the width of a human hair.
