Check out our latest paper on STIRAP of NaCs
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.

New preprint on high-efficiency STIRAP to the NaCs ground state
New preprint on NaCs excited state spectroscopy and efficient pathways for stimulated Raman adiabatic passage (STIRAP) into the rovibrational ground state of dipolar NaCs molecules. We demonstrate STIRAP efficiency of 88%. This will be helpful for the creation of ultracold high density samples of NaCs and help with high fidelity detection of NaCs in optical lattices and optical tweezers. Link: arXiv:2302.12293

Congrats to John Clauser for 2022 Physics Nobel
Sebastian and Prof. Henry Yuan from the Columbia Computer Science department comment on the history, accomplishment, and impact of John Clauser's work for quantum science and technology today. Clauser conceived his concept to experimentally test Bell's inquality while being a grad student at Columbia University in the 60s. Together with Alain Aspect and Anton Zeilinger, he received the Physics Nobel Prize 2022. Watch the video here: https://youtu.be/z-qJiNQIquc
