  We characterize the pointer states generated by the master equation of
quantum Brownian motion and derive stochastic equations for the dynamics of
their trajectories in phase space. Our method is based on a Poissonian
unraveling of the master equation whose deterministic part exhibits
soliton-like solutions that can be identified with the pointer states. In the
semiclassical limit, their phase space trajectories turn into those of
classical diffusion, yielding a clear picture of the induced quantum- classical
transition.
