We study the thermalization of a strongly coupled quantum field theory
in the presence of a chemical potential. Using the holographic
prescription, we calculate non- local operators such as the
entanglement entropy in a time- dependent background that interpolates
between AdSd+1 and AdSd+1 -Reissner-Nordstr\"om . We study the
dependence of the thermalization time on the probe length and the
chemical potential. We find two different regimes for the physics of
thermalization: non-monotonic dependence of the thermalization time on
the chemical potential for T l << 1 and monotonic for T l >> 1.
