Lower (negative) bounds on the static electric susceptibility of non-equilibrium cubic crystals
R. Dutta, P. D. Wurzner, F. Castles
We use a classical, microscopic model of point-like dipolarizable entities (a model that is standard in the case of positive polarizability) and investigate its behavior for simple…
Active metamaterials with negative static electric susceptibility
F. Castles, J. A. J. Fells, D. Isakov +3
Well-established textbook arguments suggest that static electric susceptibility must be positive in "all bodies" [1]. However, it has been pointed out that media that are not in th…
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…
Linear electro-optic effects due to high order spatial dispersion
F. Castles
Two new types of electro-optic effect that are linear in the applied electric field strength are theoretically predicted to exist in transparent dielectric crystals due to high ord…
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…
