  • Ultracold plasmas and Rydberg lattices


We participate in the International Cold Atom Network.
We are part of the POLATOM ESF Research Networking Programme.

We are part of the larger Atomic Physics and Quantum Electronics (CQT) group, at the Department of Physics, at Eindhoven University.
In the department we participate in the Network Theoretical Physics.
We also participate in the Dutch Research School of Theoretical Physics DRSTP.

Our research project From Rydberg atom to quantum bit is part of a FOM program, with is jointly operated with the Quantum gases and Quantum Information group at the University of Amsterdam.
Our Rydberg Quantum Simulator research is also funded by the Horizon 2020 European RySQ project.
Our research group Quantum gases with strong interactions was started up by an NWO-VIDI grant.

Launch Center for Quantum Materials and Technology Eindhoven (QT/e)

We are happy and proud to announce that the Center for Quantum Materials and Technology Eindhoven has been founded at Eindhoven University of Technology (TU/e). The Center will be officially opened on Friday June 29, 2018 by Prof.dr.ir Frank Baaijens, Rector Magnificus of our university. Read more.

Dynamical formation of the unitary Bose gas

We study the structure of a Bose-condensed gas after quenching interactions to unitarity. Using the method of cumulants, we decompose the evolving gas in terms of clusters. Within the quantum depletion we observe the emergence of two-body clusters bound purely by many-body effects, scaling continuously with the atomic density. As the unitary Bose gas forms, three-body Efimov clusters are first localized and then sequentially absorbed into the embedded atom-molecule scattering continuum of the surrounding depletion. These results motivate future experimental probes of a quenched Bose-condensate during evolution at unitarity.   arXiv:1805.06808
