    "abstract": "We present a method to suppress the potential roughness of a wire-based,\nmagnetic atom guide: modulating the wire current at a few tens of kHz, the\npotential roughness, which is proportional to the wire current, averages to\nzero. Using ultra-cold $^{87}{\\rm Rb}$ clouds, we show experimentally that\nmodulation reduces the roughness by at least of a factor five without\nmeasurable heating or atom loss. This roughness suppression results in a\ndramatic reduction of the damping of center of mass oscillations.",
