Suppression of Elastic Scattering Loss for Slowly Colliding Bose-Einstein Condensates
Y B. Band, J P. Burke, A Simoni, Paul S. Julienne
Partial superfluid suppression of the elastic scattering loss in atomic Bose condensed systems is significant when the ratio of the relative velocity of the wavepackets to the critical velocity is set to be close to unity, as in experiments similar to those of Maddaloni et. Al. . A comparison of our three-dimensional simulations of the collision dynamics of two 87Rb F=2 condensates in a harmonic trap, one in the MF=2 state and the other in the MF = 1 state, show that the reduction of the oscillatory center-of-mass amplitude of the MF=1 wavepacket results largely due to elastic scattering loss collisions between atoms in the two wavepackets. We show that superfluid suppression of the elastic scattering loss can be studied in detail if the number of atoms in this type of experiment is increased to the range of 0.5-2.0 x 106.
