Query: Ramp dynamics of phonons in an ion trap: entanglement generation and
  cooling   We show that the ramp dynamics of phonons in an one-dimensional ion trap can
be used for both generating multi-particle entangled states and motional state
cooling of a string of trapped ions. We study such ramp dynamics using an
effective Bose-Hubbard model which describes these phonons at low energies and
show that specific protocols, involving site-specific dynamical tuning of the
on-site potential of the model, can be used to generate entangled states and to
achieve motional state cooling without involving electronic states of the ions.
We compare and contrast our schemes for these to the earlier suggested ones and
discuss specific experiments to realize the suggested protocols.
