A model for the Pockels effect in distorted liquid crystal blue phases
F. Castles
Recent experiments have found that a mechanically distorted blue phase can exhibit a primary linear electro-optic (Pockels) effect [F. Castles \textit{et al}. Nature Mater. \textbf…
Non-polar Flexoelectrooptic Effect in Blue Phase Liquid Crystals
B. I. Outram, S. J. Elston, F. Castles +4
Blue phase liquid crystals are not usually considered to exhibit a flexoelectrooptic effect, due to the polar nature of flexoelectric switching and the cubic or amorphous structure…
Blue-phase templated fabrication of three-dimensional nanostructures for photonic applications
F. Castles, F. V. Day, S. M. Morris +8
A promising approach to the fabrication of materials with nanoscale features is the transfer of liquid-crystalline structure to polymers. However, this has not been achieved in sys…
Stretchable liquid crystal blue phase gels
F. Castles, S. M. Morris, J. M. C. Hung +10
Liquid crystalline polymers are materials of considerable scientific interest and technological value to society [1-3]. An important subset of such materials exhibit rubber-like el…
The limits of flexoelectricity in liquid crystals
F. Castles, S. M. Morris, H. J. Coles
The flexoelectric conversion of mechanical to electrical energy in nematic liquid crystals is investigated using continuum theory. Since the electrical energy produced cannot excee…
Thermodynamically Stable Blue Phases
F. Castles, S. M. Morris, E. M. Terentjev +1
We show theoretically that flexoelectricity stabilizes blue phases in chiral liquid crystals. Induced internal polarization reduces the elastic energy cost of splay and bend deform…
