We demonstrate novel methods for exciting the collective oscillations of Bose-Einstein condensates without directly deforming the confinement potential. The collective excitations were induced through the radio-frequency (rf) forced evaporative co...
We report on the detection of picosecond pulsed squeezed light generated by an optical parametric amplification in a periodically poled MgO : LiNbO(3) waveguide. By using a temporally shaped local oscillator in a balanced homodyne detection, we ob...
