      abstract     = {In the first part of this talk I will give a short
                      introduction to colloids. In the second part, the phases and
                      dynamical states that are induced by external electric
                      fields in a system of very long and thin and highly charged
                      rod-like colloids will be discussed. Experimental results on
                      suspensions of fd-virus particles within the two-phase
                      isotropic-nematic coexistence region will be presented.
                      These fd-virus particles serve as model rod-like colloids,
                      which consist of ds-DNA strands covered with about 6000 coat
                      proteins, they have a length of 880 nm, a thickness of 7 nm,
                      with a persistence length of about 2500 nm. Depending on the
                      electric field strength and the frequency, several
                      phase/state-transitions are induced: a transition from
                      nematic to chiral nematic, from a nematic to a homeotropic
                      state, and a transition to a dynamical state where nematic
                      domains persistently melt and reform. The time scale on
                      which melting and reforming occurs and the size of the
                      domains both diverge at what could be identified as a
                      “non-equilibrium critical point”. An explanation of
                      these phenomena is presented, both on an intuitive level and
                      based on the Smoluchowski equation, which is an equation of
                      motion for the probability density function for the
                      positions and orientations of the rods.},
