Theory of Ultracold Atoms and Molecules Group

Chair of Complex Systems Modeling, Faculty of Physics, University of Warsaw

General info

We work on the intersection of theoretical atomic, molecular, and optical (AMO) physics and quantum chemistry. We are primary interested in engineering novel controllable quantum molecular systems for both fundamental research and upcoming quantum technologies.

Research topics pursued by our group include:

  • Cold hybrid ion-neutral systems;
  • Formation, dynamics, and control of ultracold molecules;
  • Ultracold controlled collisions and chemical reactions;
  • Magnetically tunable Feshbach resonances in ultracold gases;
  • Quantum dynamics and simulations with quantum few- and many-body systems.

We use and develop state-of-the-art ab initio electronic structure methods of quantum chemistry, as well as computational approaches in atomic, molecular, and optical physics. We also enjoy and are very open to close collaboration with experimental groups.
