Query: Understanding of the Vortex Lattice Behavior Induced by Selective
  Removal of Atoms from a Bose-Einstein Condensate   It is known that the quantized vortices in a superfluid can be described by a
dual electromagnetic model through the duality transformation. Recently a new
technique, which can selectively remove atoms from a Bose-Einstein condensate,
was applied to the vortex lattice state of the rapid rotating Boson gases. The
increase of vortex number, dynamical formation of giant vortex, the oscillation
and damping of vortex motion were observed in these experiments. In this paper
we will discuss these observations in the framework of dual description and
show how to understood these observations naturally.
