Experimental postdoc position in ultracold quantum gases

The Ultracold Quantum Gases group at ICFO (Barcelona), led by Prof. Leticia Tarruell, is inviting applications for one postdoctoral position in experimental quantum simulation with ultracold atoms. The research will focus on unconventional superfluidity in two-component Bose-Einstein condensates with tunable and competing interactions, induced by two mechanisms that the group has demonstrated during the last years: i) the importance of beyond mean-field effects when the total mean-field energy practically cancels out, which leads to the emergence of new quantum phases stabilized by quantum fluctuations such as quantum liquid droplets [Cabrera et al. Science 2018, Cheiney et al. PRL 2018]; ii) the engineering of new types of interactions in these systems via radio-frequency or optical coupling of the two components, which very recently allowed us to expand the scope of quantum simulation to topological gauge theories [Sanz et al. PRL 2022, Frölian et al. arXiv2022]. Now, our goal is to demonstrate other unconventional superfluid phases by combining the two mechanisms, and to extend this physics to the strongly interacting regime when confining the system to lower dimensions. We are looking for excellent and highly motivated candidates with a good background in both AMO and condensed-matter physics. A PhD in the field of ultracold atoms/ions or quantum optics is required. We provide access to excellent technical facilities and a dynamical research environment with stimulating theoretical collaborations. The position is funded by EU through the ERC Consolidator Grant project SuperComp.

To apply, please send your CV and the name of two people who could provide letters of recommendation to Leticia Tarruell: leticia.tarruell@icfo.eu A formal application should also be sent through the jobs.icfo.eu portal. We aim at filling this position during 2022, but are flexible with the starting date. However, we encourage you to send an expression of interest or a full application as soon as possible.
