Ultracold atoms offer an ideal platform to explore new quantum phenomena due to their great experimental controllability and a high degree of isolation. Being the most magnetic element, dysprosium presents not only a tunable short-range contact interaction but also a competing isotropic long-range dipole-dipole interaction. Making use of this competition, novel many-body quantum states were discovered, including liquid-like droplets, droplet crystals, and most recently supersolids. Our new group, Quantum Fluids, at Heidelberg University is designing a novel compact experimental set-up which will be based on the first two-dimensional magneto-optical trap (2D-MOT) to produce a high-flux beam of slow dysprosium atoms, instead of the more standard Zeeman slower design. Additionally, combining a crossed-optical dipole trap, a tuneable accordion lattice optical trap, a tailorable in-plane trap, and a tunable magnetic environment, will give us a great opportunity to investigate many-body phenomena occurring in dipolar gases confined in two-dimensional spaces. At the Erlangen 22 conference, I would like to present the design and implementation of our 2D-MOT.
