Abstract: Abstract The optical properties of four triatomic all-dielectric metamaterial structures composed of TiO2 media are investigated numerically. Two symmetrical metamaterial structures with dark-bright-dark coupling mode and bright-dark-bright coupling mode can enhance and cancel the original… read more here.

DOI: 10.1103/physreva.96.013601
Abstract: We analyze the dynamics of two-component vector solitons, namely bright-in-dark solitons, via the variational approximation in Bose-Einstein condensates. The system is described by a vector nonlinear Schr\"odinger equation appropriate to multi-component Bose-Einstein condensates (BECs). The… read more here.

DOI: 10.1103/physrevx.9.041048
Abstract: We report that dark excitons can have a large contribution to the emission intensity in carbon nanotubes due to an efficient exciton conversion from a dark state to a bright state. Time-resolved photoluminescence measurements are… read more here.
