    "abstract": "It is shown that by an appropriate modification of the trapping potential one\nmay create collective excitation in cold atom Bose-Einstein condensate. The\nproposed method is complementary to earlier suggestions. It seems to be\nfeasible experimentally --- it requires only a proper change in time of the\npotential in atomic traps, as realized in laboratories already.",
