Qualitative aspects of the entanglement in the three-level model with photonic crystals
This communication is an enquiry into the circumstances under which concurrence and phase entropy methods can give an answer to the question of quantum entanglement in the composite state when the photonic band gap is exhibited by the presence of photonic crystals in a three-level system. An analytic approach is proposed for any three-level system in the presence of photonic ... إقراء المزيد

Photonic crystal defective superconductor and black body radiations,
In the present work, we have obtained a new design for sensing the black body radiation. In this work we designed one-dimensional photonic crystals incorporates that a high-temperature superconducting material as a defect layer. The numerical results are essentially obtained based on the fundamental characteristic matrix method. Also, the results show that the appearance of defect mode inside the photonic ... إقراء المزيد

Tunable properties of one-dimensional photonic crystals that incorporate a defect layer of a magnetized plasma

Tunable properties of one-dimensional photonic crystals that incorporate a defect layer of a magnetized plasma
In this paper, we theoretically investigate the transmittance characteristics of one-dimensional defective photonic crystal in microwave radiations based on the fundamentals of the characteristic matrix method. Here, the defect layer is magnetized plasma. The numerical results show the appearance of defect peaks inside the Photonic Band Gap. The external magnetic field has a significant effect on the permittivity of the ... إقراء المزيد
