Post-doctoral position on quantum simulation with ultracold strontium atoms

Institute of Photonic Sciences, Luxembourg

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.

During the last years, strontium is emerging as an atom of choice for quantum simulation. Due to the presence of two valence electrons, it has a rich electronic structure with two sets of optical transitions. This enables efficient cooling using a narrow-linewidth transition and simplifies fluorescence imaging using a short-wavelength and broad-linewidth transition. Moreover, the existence of a fermionic isotope with a nuclear spin of 9/2, of magical wavelengths, and of an optical clock transition, provide novel assets to expand the toolbox of quantum simulation to more complex models. In the group, we have two experiments working with cold strontium atoms. The first one exploits ground state strontium atoms in an optical lattice, and aims at investigating large spin Fermi-Hubbard models with single-atom and single-site resolution by imaging them in a quantum gas microscope. The second one focuses instead on Rydberg atom arrays generated by optical tweezers, and its goal is to engineering tunable Ising models in decorated arrays to simulate two-dimensional lattice gauge theories.

The successful candidate is expected to contribute to both setups. In the first one, the immediate goal is to extend our recently demonstrated bosonic strontium quantum-gas microscope [arXiv:2312.14818] to the fermionic isotope, to explore the SU(N) Fermi-Hubbard model. The second setup is still under development, and we aim at demonstrating the first atom arrays within the year.

This contract is funded by the European Union – NextGenerationEU (MICINN-PRTR-C17.I1) and by Generalitat de Catalunya.
