 Abstract: We theoretically investigate, within the random phase
approximation. the collective excitations of symmetric wide
quantum Wells under in-plane magnetic fields B-parallel to. We
find that the B-parallel to, field significantly affects the
frequencies, (an-)isotropy and types of the ptasmon modes. In
particular. a high B-\ can induce an additional branch of
undamped acoustic-like plasmons, which does not exist in single
quantum wells without B-parallel to. (C) 2002 Elsevier Science
