Welcome to the Porto Research Group

Research on ultra-cold atoms lies at the intersection of atomic physics, many-body physics, quantum optics and quantum information. Quantum physics dominates the behavior of atomic gases cooled to near absolute zero temperature, and cold trapped atoms provide an ideal experimental system for studying quantum many-body physics. Our research focuses on  ultra-cold gases of Rubidium atoms and Ytterbium/Rubidium mixtures, with the goals of studying novel condensed matter systems and engineering quantum control over many-body systems, including dissipative baths.

    We recently demonstrated conservative optical lattices with subwavelength spatial structure. (PRL 120 083601 (2018)) The potential is based on the nonlinear optical response of three-level atoms in laser-dressed dark states.

    Our follow-up paper to the anamalous broadening work explores the dynamics of the black-body-induced runaway broadening process. Such broadening has serious implications for many proposals to coherently use Rydberg interactions, particularly Rydberg dressing proposals.
