A double-layer harmonic diffractive element (HDE) structure is investigated and the optimization procedure is given based on the equation of diffraction efficie
Electronic properties of both Pb and S vacancy defects in PbS(100) have been studied using the first-principles density functional theory (DFT) calculations wit
We extend the idea of entanglement concentration protocol for pure states (Phys. Rev. Lett. 88, 187903) to the case of entanglement distillation for mixed state
A multiwavelength and multiangle mathematical model (MWMA) is developed, and the corresponding influence factors of the model are analysed by the numerical calc
In accordance with the intrinsic structure of controllably-spun birefringent-fibre-based fibre polarization transformer (FPT), the Jones vector is calculated fr
