  In the paper the dynamic localization of charged particle (electron) in a
quantum wire under the external non-uniform time-dependent electric field is
considered. The electrons are trapped in a deep 'dynamic' quantum wells which
are the result of specific features of the potential imposed on 2D electron
gas: the scale of spatial nonuniformity is much smaller then the electron mean
free path (L_1 << \bar{l}) and the frequency is much greater then \tau^{-1},
where \tau is the electron free flight time. As a result, the effect of this
field on the charged particle is in a sense equivalent to the effect of a
time-independent effective potential, that is a sequence of deep 'dynamic'
quantum wells were the elelctrons are confined. The possible consequeces of
this effect are also discussed and similarity with the classical Paul traps are
emphasized.
