Taming, slowing and trapping atoms with light

Welcome to the website of the Ultracold Quantum Gases group at the European Laboratory for Nonlinear Spectroscopy (LENS), the Department of Physics and Astronomy of the University of Florence (Italy) and the Institute of Optics of the Italian National Research Council (CNR - INO). In our labs we use lasers and magnetic fields to produce the lowest temperatures of the Universe, just a few billionths of a degree above absolute zero...

At these temperatures, atoms stop moving and we can control them for a variety of different fundamental studies and applications. We can force atoms to arrange according to a periodic structure and simulate the behavior of crystalline solids and new materials. We can use the atoms as ultra-high accurate sensors to probe forces with the power of quantum mechanics. We can study how quantum particles combine together under the action of strong interactions and how superfluidity develops. We can use these ultracold atoms to process information and develop new quantum technologies.

Dress warmly and... follow us for this ultracold journey!

Happy QST year!

In occasion of the International Year of Quantum Science and Technologies, the Italian National tv Rai realized a video on the reaserch activities at CNR-INO, including our work at LiLab! For this occasion we create the atomic version of the YQST logo: the few thousands of atoms in DMD-sculpted optical potential wishes you a happy QST year!

Workshop: Quantum Fluids of Light and Matter, Florence 12-14 March

We are pleased to announce a scientific workshop on Quantum Fluids of Light and Matter, jointly organized by CNR-INO and CNR-Nanotec as part of the NQSTI project (Spoke 3 and Spoke 4). The event will take place from March 12-14 at LENS (European Laboratory for Non-Linear Spectroscopy) in Florence. Researchers from Lecce (CNR-Nanotec), Florence, and Pisa (CNR-INO, University of Florence, LENS) will present their latest work on quantum fluids, exploring topics at the intersection of light-matter interactions, atomic physics, and quantum gases.

The workshop is designed to foster collaboration and stimulate new ideas, with ample time dedicated to discussions and brainstorming sessions. Participants will have the opportunity to tour the state-of-the-art labs at LENS, which specialize in atomic physics, quantum gases, and photonics, providing a unique chance to engage with cutting-edge experimental setups and techniques. This meeting aims to strengthen connections within the NQSTI community and inspire joint projects that push the boundaries of quantum science and technology. We look forward to welcoming you to Florence for this exciting exchange of knowledge and ideas.

Here you can find the full program of the event, that you can also join remotely at this link.
