Ultracold Quantum Gases Group: Post-doctoral position on quantum-gas microscopy of SU(N) ...

Mon, 14 Sep 2026 22:00:00 +0100

ICFO is offering a postdoctoral position to a well-qualified, highly motivated and dynamic young scientist who wishes to enhance his/her scientific career in a friendly and stimulating environment. The successful candidate will be joining the Ultracold Quantum Gases group led by Prof. Dr.Leticia Tarruell . The Fermi-Hubbard model is a cornerstone model of condensed matter physics. It describes the physics of strongly-correlated materials, quantum magnets, and might hold the key of high-temperature superconductivity. Investigating its low-temperature many-body phases is extremely challenging using classical computers and, as a result, many of them remain poorly understood. UItracold atoms trapped in optical lattices provide a pristine realization of the Hubbard model and hold the promise of solving many of its puzzles in a quantum simulation approach. Moreover, they allow one to engineer and investigate even richer variants of the model, which go beyond the realm of existing materials. In our group, we are interested in exploring a particularly intriguing one: the SU(N) Fermi-Hubbard model. It describes fermions of spin N and SU(N)-symmetric interactions, for which intricate magnetic orders and exotic spin liquid phases have been predicted. It can be realized using atoms with two valence electrons, such as ytterbium or strontium. To investigate such SU(N) physics, our group has developed a quantum-gas microscope that allows one to perform single-atom and single-site resolved fluorescence images of strontium Hubbard systems for the first time. Furthermore, we have very recently been able to push our setup to obtain spin-resolved images of fermionic systems with N up to 10. The successful candidate for this position will join a small team of PhD and post-doctoral researchers working to elucidate the mysteries of the SU(N) Fermi-Hubbard model and its low-temperature phases at the microscopic level.
