Fermions with tunable interactions... In the lithium lab we produce ultracold Fermi gases of 6Li to explore out-of-equilibrium dynamics and transport phenomena in strongly correlated fermionic matter. Atoms are confined into light-imprinted potential structures, simulating the motion of electrons in solid state devices. Our main goal is the study of two-dimensional strongly correlated phases, such as superfluidity across the BCS-BEC crossover and its robustness to disorder.

Merry Christmas!

Li Lab

We wish you relaxing holidays and a fantastic New Year!

We created this Christmas card with our new homogeneous unitary Fermi gas in tailored optical potentials. The gas is trapped in a 3D box potential created by two DMDs shining repulsive light both in the vertical and in the horizontal directions. Each frame consist in a single-shot image of the unitary gas with sculpted optical potential with the vertical DMD, imaged with our high-resolution microscope objective. We divide each frame into 16 or 20 segments to exploit the full resolution of the optical setup to accurately reproduce the videos on our atomic display.  

Feliz Navidad! Buon Natale!
