Query: Parametric Resonance Phenomena in Bose-Einstein Condensates: Breaking of
  Macroscopic Quantum Self-Trapping   We analyze the periodic tunneling of a Bose-Einstein condensate in a
double-well potential which has an oscillating energy barrier. We show that the
dynamics of the Bose condensate critically depends on the frequency $\omega$ of
the oscillating energy barrier. In the regime of periodic macroscopic quantum
tunneling (PMQT) with frequency $\omega_J$, the population imbalance of the
condensate in the two wells can be enhanced under the condition of parametric
resonance $\omega = 2 \omega_J$. Instead, in the regime of macroscopic quantum
self-trapping (MQST), we find that MQST can be reduced or suppressed under the
condition of parametric resonance between the frequency $\omega$ of the energy
barrier and the frequency $\omega_{ST}$ of oscillation through the barrier of
the very small fraction of particles which remain untrapped during MQST.
