In this presentation, the phase/state behavior of very long and thin, highly charged rod-like colloids (fd-virus particles) under oscillating external electric fields is discussed. Fd-virus suspensions exhibit an isotropic-nematic phase transition. For concentrations of fd-virus particles within the two-phase isotropic-nematic coexistence region, various field-induced phase transitions and dynamical states are observed, depending on the field-amplitude and frequency. A non-chiral nematic, a chiral nematic, a homeotropically aligned homogeneous phase, and a dynamical state where non-chiral nematic domains persistently melt and form are observed. The molecular origin of the various phases is discussed, and a semi-quantitative theory is presented for the dynamical state.}, month = {Jun}, date = {2015-06-23}, organization = {Institutsseminar, CPG, Vienna (Austria), 23 Jun 2015 - 23 Jun 2015}, subtyp = {Invited}, cin = {ICS-3}, cid = {I:(DE-Juel1)ICS-3-20110106}, pnm = {551 - Functional Macromolecules and Complexes (POF3-551)}, pid = {G:(DE-HGF)POF3-551}, typ = {PUB:(DE-HGF)31}, url = {https://juser.fz-juelich.de/record/202638}, }
