Заглавие : Влияние электромагнитно индуцированной прозрачности на спектр дефектных мод одномерного фотонного кристалла
Место публикации : Квантовая электроника. - Москва: Федеральное государственное бюджетное учреждение науки Физический институт им. П.Н. Лебедева Российской академии наук, 2009. - Т. 39, № 2. - С. 157-162. - ISSN 0368-7147
Аннотация: Изучен спектр пропускания одномерного фотонного кристалла (ФК) с дефектом из материала, в котором возможна электромагнитно индуцированная прозрачность. Анализ выполнен с учетом пространственной неоднородности взаимодействующих полей в ФК. Установлено, что спектр пропускания такого ФК зависит от пространственного перекрытия дефектных мод, возбуждаемых пробным и управляющим излучениями. Показано, что электромагнитно индуцированная прозрачность может приводить к значительному сужению спектра дефектной моды.

Ключевые слова (''Своб.индексиров.''): borates--"lu-ban stool"-like structure--ultraviolet transparency--zero--linear compressibility
Аннотация: Discovering materials that exhibit zero linear compressibility (ZLC) behavior under hydrostatic pressure is extremely difficult. To date, only a handful of ZLC materials have been found, and almost all of them are ultrahard materials with densified structures. Here, to explore ZLC in nondense materials, a structural model analogous to the structure of the “Lu‐Ban stool,” a product of traditional Chinese woodworking invented 2500 years ago, is proposed. The application of this model to borates leads to the discovery of ZLC in AEB2O4 (AE = Ca and Sr) with the unique “Lu‐Ban stool”‐like structure, which can obtain a subtle mechanical balance between pressure‐induced expansion and contraction effects. Coupled with the very wide ultraviolet transparent windows, the ZLC behavior of AEB2O4 may result in some unique but important applications. The applications of the “Lu‐Ban stool” model open a new route for pursuing ZLC materials in nondense structural systems.

Аннотация: We study the interaction of two photons in a Rydberg atomic ensemble under the condition of electromagnetically induced transparency, combining a semiclassical approach for pulse propagation and a complete quantum treatment for quantum state evolution. We find that the blockade regime is not suitable for implementing photon-photon cross-phase modulation due to pulse absorption and dispersion. However, approximately ideal cross-phase modulation can be realized based on relatively weak interactions, with counterpropagating and transversely separated pulses.

Аннотация: Half-metallic ferromagnetic materials with planar forms are promising for spintronics applications. A wide range of 2D lattices like graphene, h-BN, transition metal dichalcogenides, etc. are non-magnetic or weakly magnetic. Using first principles calculations, the existence of graphene-like hexagonal chromium nitride (h-CrN) with an almost flat atomically thin structure is predicted. We find that freestanding h-CrN has a 100% spin-polarized half-metallic nature with possible ferromagnetic ordering and a high rate of optical transparency. As a possible method for stabilization and synthesis, deposition of h-CrN on 2D MoSe2 or on MoS2 is proposed. The formation of composites retains the half-metallic properties and leads to the reduction of spin-down band gaps to 1.43 and 1.71 eV for energetically favorable h-CrN/MoSe2 and h-CrN/MoS2 configurations, respectively. Calculation of the dielectric functions of h-CrN, h-CrN/MoSe2 and h-CrN/MoS2 exhibit the high transparency of all three low-dimensional nanomaterials. The honeycomb CrN may be considered as a promising fundamental 2D material for a variety of potential applications of critical importance. © The Royal Society of Chemistry 2017.

Аннотация: The feasibilities and specific features of coherent nonlinear-optical energy transfer from control fields to a negativephase signal are studied, and they are found to stem from the backwardness of electromagnetic waves inherent to negative-index metamaterials. Plasmonic metamaterials that possess negative group velocity for light waves promise a revolutionary breakthrough in nanophotonics. However, strong absorption inherent to such metaldielectric nanocomposites imposes severe limitations on the majority of such applications. Herein we show the feasibility and discuss different nonlinear-optical techniques of compensating such losses, producing transparency, amplification and even generation of negative-phase light waves in originally strongly absorbing microscopic samples of plasmonic metal-dielectric nanostructured composites. © 2009 SPIE.

Аннотация: Intrinsic isotropic near-zero thermal expansion is discovered in borate crystal Zn4B6O13 with high transparency in the ultraviolet region. First-principles calculations demonstrate that the very low thermal expansion originates mainly from the invariability of the solid [B24O48] truncated octahedra that are fixed by the [Zn4O13] clusters in the ZBO structure.
