abstract = {Electric-field induced phase/state transitions are observed
in AC electric fields with small amplitudes and low
frequencies in suspensions of charged fibrous viruses (fd),
which are model systems for highly charged rod-like
colloids. Texture- and particle-dynamics in these
field-induced states, and on crossing transition lines, are
explored by image time-correlation and dynamic light
scattering, respectively. At relatively low frequencies,
starting from a system within the isotropic-nematic
coexistence region, a transition from a nematic to a chiral
nematic is observed, as well as a dynamical state where
nematic domains melt and reform. These transitions are
preliminary due to field-induced dissociation/association of
condensed ions. At higher frequencies a uniform state is
formed that is stabilized by hydrodynamic interactions
through field-induced electro-osmotic flow where the rods
align along the field direction. There is a point in the
field-amplitude vs. frequency plane where various transition
lines meet. This point can be identified as a
“non-equilibrium critical point,” in the sense that a
length scale and a time scale diverge on approach of that
point. The microscopic dynamics exhibits discontinuities on
crossing transition lines that were identified independently
by means of image and signal correlation spectroscopy.},
