Abstract Two-dimensional (2D) quantum gases are produced from three-dimensional (3D) gases strongly confined in one direction of space. Usually, the strong confinement is produced by an optical lattice which results in a harmonic trapping potential for the atomic cloud. The condition for reaching the 2D regime will depend on the comparison between the thermal energy of the atomic cloud and the ground-state energy of the harmonic potential. In the case of a lattice with tunable interfringe spacing, it is possible to dynamically change the dimensionality of the system. In this project, we propose to study the transition from three- to two-dimensions in a quantum gas made of potassium-39 atoms. For that purpose, we will excite the breathing mode of the atomic cloud trapped in a crossed optical dipole trap under different compressions of the strong confinement similar to the results obtained in the case of a Fermi gas. | |
