**The tilted smectic liquidโcrystal phase** of an esterโbased bentโcore mesogen (see Figure) is optically isotropic due to the combination of suitable tilt and opening angles of the bent cores. In electric fields, Vโshaped switching between isotropic and birefringent states is observed. Both the ant

When two photons are coded into entangled polarization states, one of the eigenstates of the direct product of the fiber transfer function matrix is found to be independent of the transmission fiber birefringence. The eigenstate is the entangled singlet state < , one of the Bell states. The entangle
**Dithienyletheneโcontaining glassy nematic liquid crystals** (see Figure) have been synthesized, in which the dithienylethene coreโs electronic transition moment is uniaxially aligned. Large changes in refractive index and optical birefringence could be induced in the solid state by photochemical m
