Query: Fast control of topological vortex formation in BEC by counter-diabatic
  driving   Topological vortex formation has been known as the simplest method for vortex
formation in BEC of alkali atoms. This scheme requires inversion of the bias
magnetic field along the axis of the condensate, which leads to atom loss when
the bias field crosses zero. In this Letter, we propose a scheme with which the
atom loss is greatly suppressed by adding counter-diabatic magnetic field. A
naive counter-diabatic field violates the Maxwell equations and we need to
introduce an approximation to make it physically feasible. The resulting field
requires an extra currents, which is experimentally challenging. Finally we
solve this problem by applying a gauge transformation so that the
counter-diabatic field is generated by controlling the original trap field with
the additional control of the bias field.
