  The quantum dynamics of a few bosons in a double well potential is studied
using a Bose Hubbard model. We consider both signs for the on-site
interparticle interaction and also investigated the situations where they are
large and small. Interesting distinctive features are noted for the tunneling
oscillations of these bosons corresponding to the above scenarios. Further, the
sensitivity of the particle dynamics to the initial conditions has been
studied. It is found that corresponding to an odd number of particles, such as
three (or five), an initial condition of having unequal number of particles in
the wells has interesting consequences, which is most discernible when the
population difference between the wells is unity.
