| Research Abstract |
We have developed various experimental methods using cold atoms towards the realization of the high precision quantum measurements based on using atom interferometers with quantum degenerated atoms, as follows. 1) We have developed a method for fast all-optical production of Rb BEC. 2) We observed a Rydberg blockade effect between two Rb atoms in a dipole trap. 3) We observed a enhanced momentum transport in cold Rb atoms using an phase modulated pulsed lattice potential. 4) We have developed a precision gravimeter using an atomic interferometer with laser cooled Rb atoms.
