A Discotic Disguised as a Smectic: A Hybrid Columnar Bragg Glass
A Discotic Disguised as a Smectic: A Hybrid Columnar Bragg Glass
We show that discotics, lying deep in the columnar phase, can exhibit an x-ray scattering pattern which mimics that of a somewhat unusual smectic liquid crystal. This exotic, new glassy phase of columnar liquid crystals, which we call a "hybrid columnar Bragg glass," can be achieved by confining a columnar …
