    "abstract": "We report the implementation of a two-dimensional Raman cooling scheme using\nsequential excitations along the orthogonal axes. Using square pulses, we have\ncooled a cloud of ultracold Cesium atoms down to an RMS velocity spread of\n0.39(5) recoil velocity, corresponding to an effective temperature of 30 nK\n(0.15 T_rec). This technique can be useful to improve cold atom atomic clocks,\nand is particularly relevant for clocks in microgravity.",
