Chiral-induced polarization at a tilted nematic — substrate interface
An ac electric field at frequency ω is applied to a chiral nematic liquid crystal whose director is tilted by an angle θi with respect to the substrate normal. The nematic director is observed to oscillate at frequency ω azimuthally about the substrate normal, indicating the existence of a component of polarization Pi at the substrate that is perpendicular to the director and parallel to the su...
متن کاملSurface-induced polarization at a chiral-nematic-substrate interface.
A chiral nematic liquid crystal that is tilted by an angle θi with respect to a substrate is subjected to an ac electric field at frequency ω. The nematic director is found to oscillate azimuthally about the normal to the liquid crystal substrate interface at frequency ω, indicating that a nonzero polarization perpendicular to the molecular tilt plane exists at the interface. The interfacial po...
متن کاملPolarization at the gold/pentacene interface
Direct and inverse photoemission spectroscopy are used to investigate the electronic polarization P = P + P induced by the pentacene anion and cation at the Au/pentacene interface. Based on the spectroscopic measurements and on previously published calculations, we determine that the total polarization at the metal interface is approximately 0.67 eV larger than at the surface of the pentacene f...
متن کاملRefraction at the Interface of a Lossy Metamaterial
The refraction phenomenon at the interface of an ordinary material and a lossy metamaterial has been investigated. For oblique incidence on the lossy metamaterial, the planes of constant amplitude of the refracted wave are parallel to the interface and the plane of constant phases make a real angle with the interface (real refraction angle). The real refraction angle and hence, the real refract...
متن کاملParahydrogen-induced polarization at zero magnetic field.
We use symmetry arguments and simple model systems to describe the conversion of the singlet state of parahydrogen into an oscillating sample magnetization at zero magnetic field. During an initial period of free evolution governed by the scalar-coupling Hamiltonian HJ, the singlet state is converted into scalar spin order involving spins throughout the molecule. A short dc pulse along the z ax...
