I will present a new experimental setup designed to investigate properties of ultracold bosons in low dimensions. In this setup, we produce a degenerate gas of rubidium atoms vertically confined into a single plane in an optical accordion. In the horizontal plane, we are able to engineer a flat-bottom potential whose shape can be chosen at will (disc, square, rings, boxes) by imaging the surface of a Digital Mirror Device (DMD). Thanks to this versatile system we aim at studying bosonic transport as well as implementing artificial gauge fields. I will present the first results that we have obtained in these directions.
