Optically trapped, ultra-cold atoms provide a natural platform for quantum simulation and quantum computing. In this project, we use cold 87Rb atoms trapped in dynamic optical lattices to study many-body physics and to explore experimental quantum control of atom states.
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.
This project, jointly led by Steve Rolston and Trey Porto, uses strong photon-photon interactions mediated by Rydberg atoms for quantum netwo
Mixtures of ultracold atoms provide a range of opportunities for cold atom research beyond single-species experiments. In this project we use mixtures of 87Rb and Yb atoms to study quantum gas mixtures.

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.
