    "abstract": "A dense gas of cesium atoms at the crossover to two-dimensionality is\nprepared in a highly anisotropic surface trap that is realized with two\nevanescent light waves. Temperatures as low as 100nK are reached with 20.000\natoms at a phase-space density close to 0.1. The lowest quantum state in the\ntightly confined direction is populated by more than 60%. The system offers\nintriguing prospects for future experiments on degenerate quantum gases in two\ndimensions.",
