Magnon dark mode, which possesses long coherence time, has been observed in transmission experiments of a microwave cavity loaded with two yttrium iron garnet spheres. Due to sublattice magnetizations, it seems likely exhibit magnon mode an isolated antiferromagnet (AFM). To demonstrate such possibility, we developed distinct approaches based on the magnon-photon Hamiltonian AFM-embedded and transfer matrix method, respectively. The numerical analytical results show that can not be obtained...
We develop a systematic analytical approach to study the linear and nonlinear solitary excitations of quasi-one-dimensional Bose-Einstein condensates trapped in an optical lattice. For case, Bloch wave nth energy band is superposition Mathieu's functions ce_{n-1} se_{n} ; gap ce_{n} . only solitons inside gaps are likely be generated there two types solitons-fundamental (which localized stable state) subfundamental but unstable state). In addition, we find that pinning position amplitude...
A theoretical model based on the band bending theory was developed for explaining field-emission mechanism of wide-band gap semiconductors (WBGSs). It shown that maximum value bending, which is nearly linearly proportional to WBGSs, may amount a few eV. Furthermore, calculated energy distribution combined with analyzed cubic boron nitride (c-BN) as typical one indicated electron emission originates from conduction minimum resulting bending. These results present perspective explain...
We investigated theoretically the resonant splitting of ballistic conductance peaks in magnetic superlattices. It is found that, for superlattices with periodically arranged n identical barriers, there exists a general $(n\ensuremath{-}1)$-fold peak rule conductance, which analogy transmission n-barrier electric [R. Tsu and L. Esaki, Appl. Phys. Lett. 22, 562 (1973)].
Eu3+ -doped transparent glass ceramics containing MF2 (M = Ba, Ca, Sr) nanocrystals were fabricated using a melt-quenching method, and the resulting structures studied X-ray diffraction. Levels 5 D1 D0 of ions verified as thermally coupled levels fluorescence intensity ratio method. The ratios, optical temperature sensitivity thermal quenching ratios function temperature. With an increase in temperature, relative (SR ) decreased sharply at first, then slowly increased, before finally...
Space truss structures are essential components for space-based remote sensing loads with high spatial and temporal resolutions. To achieve high-precision vibration control, an accurate efficient dynamics model is essential. In addition to the current equivalent beam (EBM) based on classical continuum theory, improved (IEBM) proposed that considers impact of distinction between trusses beams torsional shear deformations, as well deformation flexural rigidity. According displacement...
The covalent interactions between proanthocyanidins (PAs) and pectin during thermal processing was investigated. An acid-butanol assay clearly showed that PAs were covalently bound to pectin. Computational studies indicated a nucleophilic substitution reaction occurred the carbocation generated by carboxyl or hydroxyl groups on pectin, leading formation of PAs-pectin adducts. Thermal significantly affected physicochemical, functional, biological properties reduced molecular weight increased...
By using the quasidiscrete multiple-scale method, we study nonlinear properties of a monoatomic chain with Kac–Baker-like long-range harmonic interaction. Besides usual asymmetric envelope solitons, novel nonliear elementary excitation, hole-soliton, is analytically derived. It found that dispersion relation and group velocity exhibit some characters different from without Furthermore, these solitons are nonpropagating at other sites except for center Brillouin zone, soliton zone supersonic.
We have preformed a first-principle calculation on the electronic transport properties of recently synthesized nanotubelike fullerene D5h(1)-C90. One finds three negative differential resistance regions in I-V curve, which could be modulated by gate voltage and contact configuration. Further analysis showed that, charge transfer molecule-electrode coupling, induced both bias voltages, are responsible for observed phenomena.
By using the method of multiple-scale and continuum approximation, we study nonlinear properties a monoatomic chain with Kac–Baker-like long-range harmonic interaction. It is shown that dispersion relation, group velocity amplitude solitons exhibit some new characters different from without
AbstractA series of Er3+, Sm3+ and Er3+/Sm3+ codoped BaGdF5 nanocrystalline phosphors have been successfully synthesised by hydrothermal synthesis. Uniformly distributed nanocrystals with a spherical morphology particle size 30–40 nm were observed. X-ray diffraction, field emission scanning electron microscopy, transmission photoluminescence decay studies employed to characterise the samples. Under 382 radiation excitation, BaGdF5:Er3+ samples exhibit typical green band Er3+ ions. With...
By developing a multiple-scale method, we study analytically the dynamics of soliton inside semi-infinite band gap (SIBG) quasi-one-dimensional Bose–Einstein condensates trapped in an optical lattice. In linear case, stable condition formation is obtained. For weak nonlinearity, whether there occurs spatially propagating or localized determined by lattice depth. Meanwhile, predict existence dark (bright) solitons for repulsive (attractive) interactions SIBG, different from that other energy...
