Momentum-Transfer to and Elementary-Excitations of a Bose-Einstein Condensate by a Time-Dependent Optical Potential

Y. B. Band, M. Sokuler

We present results of calculations on Bose-Einstein condensed ${}^{87}$Rb atoms subjected to a moving standing-wave light-potential of the form $V_L(z,t)=V_0(t)\cos (qz-\omega t)$. We c…
