Query: Kicked Dirac particle in a box   We study quantum dynamics of a kicked relativistic spin-half particle in a
one dimensional box. Time-dependence of the average kinetic energy and
evolution of the wave packet are explored. Kicking potential is introduced as
the Lorentz-scalar, i.e., through the mass-term in the Dirac equation. It is
found that depending on the values of the kicking parameters E(t) can be
periodic, monotonically growing and non-periodic function of time. Particle
transport in the system is studied by considering spatio-temporal evolution of
the Gaussian wave packet.Splitting of the packet into two symmetric parts and
restoration of the profile of the packet is found.
