A theoretical model has been developed to describe the behavior of exciton polaritons in a wide quantum well for structures
with the zinc blende symmetry in a transverse magnetic field (the Voigt geometry). The model takes into account the mixing
of the 1s-1s and 1s-2p states of heavy excitons by the magnetic field and makes it possible to explain and quantitatively describe the activation
of optically inactive states in the reflection spectra and the magnetic-field-induced increase in the translational mass of
the exciton. The quantitative calculations of the spectra have been preformed using typical parameters for CdTe/ZnCdTe quantum-well
structures. 相似文献

The Wess-Zumino model involving a renormalizable interaction potential and possessing R symmetry is considered. It is shown that an R soliton, which is a nontopological soliton state, is present in this model. Characteristic properties of the R soliton are discussed. Problems associated with the stability of the R soliton are considered. The results obtained by numerically calculating the energy and the charge of the R soliton are presented for several values of the model parameters. The scalar field configurations in this supersymmetric
model are characterized by the presence of fermionic zero modes. Expressions for the fermionic zero modes of the R soliton are obtained, and some of their properties are considered. 相似文献

The narrow-band radiation observed in the range of the resonance line of xenon at 147 nm in the VUV emission spectra of the
gas-discharge plasma of a krypton-xenon mixture is proposed to interpret as a manifestation of bound-bound transitions between
the vibrational levels of the excited electronic states 0+(3
P

P
1) and the ground electronic state 0+(1
S
0) in the KrXe* molecule. A correction of the potential curves of the electronic states under consideration is proposed from
a comparison of the calculated and experimental spectra. 相似文献

Potential curves of the ground state of the KrXe molecule and its excited states that converge to the Kr(4p 6 1 S 0) + Xe(5p 56s 3 P 1) atomic states are corrected and tested using the results of modeling published vacuum ultraviolet spectra of a gas-discharge plasma of a krypton/xenon mixture. 相似文献

Results from studying the formation and restructuring of 2d domain patterns with Pab2 symmetry are presented. A specific feature of these patterns is that they can formed and remain stable for long periods of time in a zero bias field, making it easier to use domain patterns in magneto-optical devices. A method for finding the region of domain pattern formation with Pab2 symmetry is tested. The turning of a domain pattern at a target angle under the effect of a series of magnetic pulses is detected. 相似文献

The processes accompanying the formation of ytterbium films on the Si(111) surface at room temperature are investigated by the contact potential difference method, Auger electron spectroscopy, low-energy electron diffraction, and thermal desorption spectroscopy. It is shown that the grown metal films are uniform in thickness and that Si atoms virtually do not dissolve in the films. The atoms of the silicon substrate can diffuse in limited amounts into the Yb metal film only when the surface is bombarded by high-energy primary electron beams employed in Auger electron spectroscopy. The results obtained permit the conclusion that the previously observed oscillations of the work function in Yb-Si(111) thin-film structures cannot originate from dissolution of silicon atoms in the ytterbium film. 相似文献

The review summarizes the results of the recent author’s research on the synthesis of triple-decker complexes with bridging
borole ligand. Electrophilic stacking of sandwich compounds with [(ring)M]
n+ (n = 1, (ring)M = (C5R5)Ru, (C4Me4)Co; n = 2, (ring)M = Cp*Co, Cp*Rh, etc.) cationic fragments were used as a general method of synthesis of the complexes. The influence of the substituent at the
boron atom on the course of stacking reactions is discussed. The spectral, structural, and electrochemical properties of the
complexes synthesized are also considered.

Photochemical arene exchange in the ferracarborane complex [1-(η-C6H6)-12-ButNH-1,2,4,12-FeC3B8H10]+

The benzene complex [1-(η-C6H6)-12-ButNH-1,2,4,12-FeC3B8H10]+ (3a) was synthesized by the photochemical reaction of [(η5-C6H7)Fe(η-C6H6)]+ (1) with the anion [7-ButNH-7,8,9-C3B8H10]− followed by the treatment of ferracarborane 1-(η5-C6H7)-12-ButNH-1,2,4,12-FeC3B8H10 (2) with hydrochloric acid. The benzene ligand in cation 3a is replaced by alkyl-substituted benzenes under visible light irradiation in CH2Cl2 to form [1-(η-C6R6)-12-ButNH-1,2,4,12-FeC3B8H10]+ (3b–e; C6R6 is toluene (b), mesitylene (c), hexamethylbenzene (d), or anisole (e)). The structure of [3c]PF6 was established by X-ray diffraction. 相似文献
