    "abstract": "We consider the dephasing of two internal states |0\u003e and |1\u003e of a trapped\nimpurity atom, a so-called atomic quantum dot (AQD), where only state |1\u003e\ncouples to a Bose-Einstein condensate (BEC). A direct relation between the\ndephasing of the internal states of the AQD and the temporal phase fluctuations\nof the BEC is established. Based on this relation we suggest a scheme to probe\nBEC phase fluctuations nondestructively via dephasing measurements of the AQD.\nIn particular, the scheme allows to trace the dependence of the phase\nfluctuations on the trapping geometry of the BEC.",
