Abstract :
In this study, Berry´s phases for various rotations of the Bloch vector were measured using a time-domain atom interferometer. Sodium atoms were cooled down less than 200 propK by the polarization gradient cooling and released from trap at almost zero magnetic field. Several geometrical manipulation of two-level atoms were demonstrated and examined.
