Resumen:
We study the dynamics of an inhomogeneous Bose-Einstein condensate
subject to a one-dimensional harmonic trap and a moving random potential
of finite extent. Above the critical velocity, a part of a condensate
glues to the moving random potential with a consequent displacement of
the condensate center-of-mass along the harmonic trap. We show that the
center-of-mass turning point provides a direct measure of the average
drag force acting on the condensate.
