Chiral index
WebJan 12, 2009 · We experimentally demonstrate a chiral metamaterial exhibiting negative refractive index at terahertz frequencies. The presence of strong chirality in the terahertz metamaterial lifts the degeneracy for the two circularly polarized waves and allows for the achievement of negative refractive index without requiring simultaneously negative … WebOct 1, 2024 · An SiNT is represented by two chiral indices (n,m), thus determining a chiral vector C h = na 1 +ma 2, where a 1 and a 2 are the two lattice vectors in the silicene, as …

WebSep 24, 2014 · In periodically driven lattice systems, the effective (Floquet) Hamiltonian can be engineered to be topological; then, the principle of bulk-boundary correspondence guarantees the existence of robust edge states. However, such setups can also host edge states not predicted by the Floquet Hamiltonian. The exploration of such edge states and … WebApr 14, 2024 · Supramolecular chiral emergence from achiral molecules is studied using newly designed amphiphilic polypeptides upon self-assembling into nanosheets and vesicles in water.

WebOptical rotation, also known as polarization rotation or circular birefringence, is the rotation of the orientation of the plane of polarization about the optical axis of linearly polarized light as it travels through certain materials. Circular birefringence and circular dichroism are the manifestations of optical activity.Optical activity occurs only in chiral materials, those … WebNegative refraction is the electromagnetic phenomenon where light rays become refracted at an interface that is opposite to their more commonly observed positive refractive properties. Negative refraction can be obtained by using a metamaterial which has been designed to achieve a negative value for (electric) permittivity (ε) and (magnetic) …
WebChirality (physics) A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality ). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality. A symmetry transformation between the two is called ... daughter of leda and zeusWebApr 12, 2024 · This work describes the synthesis, photophysical and chiroptical properties of a new carbazole-naphthalimide donor–acceptor pair designed to induce circularly polarized thermally activated delayed fluorescence (CP-TADF).
