    "abstract": "We report on the first measurement of a temperature dependence of the\nCasimir-Polder force. This measurement was obtained by positioning a nearly\npure 87-Rb Bose-Einstein condensate a few microns from a dielectric substrate\nand exciting its dipole oscillation. Changes in the collective oscillation\nfrequency of the magnetically trapped atoms result from spatial variations in\nthe surface-atom force. In our experiment, the dielectric substrate is heated\nup to 605 K, while the surrounding environment is kept near room temperature\n(310 K). The effect of the Casimir-Polder force is measured to be nearly 3\ntimes larger for a 605 K substrate than for a room-temperature substrate,\nshowing a clear temperature dependence in agreement with theory.",
