Query: Anisotropy-driven transition from collisionless to collisional regime in
  the dipolar modes of a trapped gaseous mixture   We evaluate the dipolar oscillations of a harmonically trapped fermion gas
containing thermal bosonic impurities as a function of the anisotropy of the
trap, from the numerical solution of the Vlasov-Landau equations for the
one-body phase-space distribution functions. Starting from a situation in which
the two components of the gaseous mixture perform almost independent
oscillations inside a spherical trap, we demonstrate that different collision
behaviors arise for oscillations in different directions as the trap is
deformed into an elongated cigar-like shape. An increase in the anisotropy of
the confinement thus suffices to drive a transition of dipolar modes from a
collisionless to a collisional regime.
