Query: Continuous melting of a driven two-dimensional flux lattice with strong
  pins   The phase diagram of a driven two-dimensional vortex lattice in the presence
of dense quasi-point pins is investigated. The transition from the crystal to
the liquid is found continuous at intermediate inductions. The correlations in
the pseudo random force that allow for an uncomplete unbinding of the
dislocations is proposed as a key mechanism to account for the continuous
transition.
