AbstractThe dynamic structure factor of a Bose-Einstein condensate in an optical lattice, momentum and energy rates imparted to the condensate are analyzed in detail as the function of both the lattice depth and the strength of the two-body interaction. Our investigation shows that the lattice depth strongly affects the dynamic structure factor. An oscillating behavior of both the static structure factor and excitation strength as a function of the momentum transfer has been developed. We also show how interatomic interaction affects these processes and discuss the conditions for possible experimental realization.
