The Will Lab investigates quantum systems of ultracold atoms and molecules. We cool atoms and molecules to ultracold temperatures just a sliver above absolute zero - reaching the coldest temperatures allowed by nature. Close to absolute zero temperature, the behavior of particles is ultimately determined by the laws of quantum mechanics. Using the precision tools of atomic physics, we have full control over the quantum state of each particle and the interactions between them. 

With ultracold atoms and molecules we create novel many-body quantum systems, perform quantum simulations of strongly interacting matter, and work towards single atom and single molecule control. Our research program focusses on fundamental questions in many-body quantum physics, quantum simulation, and quantum optics, and contributes to the development of modern quantum technologies.

A New Approach to Cold Strontium Beams

In this preprint, we present a new cold atom source for strontium based on a two-dimensional magneto-optical trap (2D MOT) that is directly loaded from the atom jet of a dispenser. The design addresses the importnat challenge of reducing the complexity of cold beam sources for strontium, which is relevant for optical atomic clocks and quantum simulation and computing devices based on ultracold Sr. Thanks to Minho and Aaron and the entire team for driving forward this approach! https://arxiv.org/abs/2210.14186

Ultracold NaCs Ground State Molecules!

Our latest preprint just appeared on arxiv reporting the first ultracold gases of NaCs ground state molecules ⚛️-⚛️. Ultracold gases of dipolar NaCs molecules open new exciting opportunities for quantum simulation and quantum information - and we cannot wait to explore them. Thanks a lot to the  NaCs team for all the amazing work that led to this!

Metasurface Holographic Optical Traps for Ultracold Atoms

In this work, we propose metasurface holograms as a novel platform to generate optical trap arrays for cold atoms with high fidelity, efficiency, and thermal stability. We have characterized the resulting patterns of light which may find potential applications in atomic clocks, quantum optics, quantum simulation and quantum computing. Thank you to the entire team, especially to our collaborators from the Asenjo-Garcia and Yu groups! https://arxiv.org/abs/2210.07425

New Quantum Simulation and Computing Lab Course

We started the new "Quantum Simulation and Computing Lab" course this semester. Students gain hands-on experience with entangled photon pairs, learn about quantum computing hardware, quantum algorithms, and how to program quantum computers. Thanks a lot to our TA team - Aden, Joseph, Shuhan, and Arjun - for making it a great success! Here an article in Columbia News.
