Аннотация: We study dynamical correlations of two coupled large spins depending on the time and on the spin quantum numbers. In the high-temperature approximation, we obtain analytical expressions for the mutual informations, quantum and classical parts of correlations. The latter was obtained performing the non-orthogonal projective (POVM) measurements onto the spin coherent states of two spins or one spin, as well as by means of the orthogonal projective measurement of von Neumann. Contribution from quantum correlations is much less than that from classical ones and decreasing with the increase in spin quantum numbers at short times. However, it is not so in a time equal to half of the quantum period. © 2012 SPIE.

Аннотация: We study the dynamical correlations between two coupled spins depending on time and the value of the spin quantum numbers. In the high-temperature approximation, we obtain analytic expressions for the mutual information and the quantum and classical parts of correlations. We consider both orthogonal and nonorthogonal measurements in the basis of spin coherent states. We show that at small times, the quantum part of correlations becomes much less than the classical part as the spin quantum numbers increase, while the situation is quite different at times equal to half the quantum period.

Аннотация: The quantum properties of dynamic correlations in a system of an electron spin surrounded by nuclear spins under the conditions of free induction decay (FID) and spin echo have been studied. Analytical results for the time evolution of mutual information, classical part of correlations, and quantum part characterized by quantum discord have been obtained within the central spin model in the high-temperature approximation. The same formulas describe the quantum discord in both the FID and the spin echo although the forms of the dependences are different because of difference in the parameters entering into the formulas. Discord of the spin echo compared with the FID has a strong dependence on time at short times, and it tends to zero with decreasing of the magnetic field, whereas in the case of the FID it reaches a plateau.

Аннотация: We consider the problem of time-optimal control of quadrupole nucleus with the spin I = 1 by NMR. In contrast to the conventional methods based on selective pulses, the control is implemented using nonselective pulses separated by free-evolution intervals. Using the Cartan decomposition, the system of equations is obtained for finding parameters of a control field. Partial time-optimal solutions for the important single-qutrit gates (selective rotations and quantum Fourier transform) are found. The strong dependence of minimum gate implementation times on global phase of the gate is observed. The analytical values of minimum times are consistent with the numerical data.

Аннотация: In this paper, methods for retrieving soil moisture, roughness, and temperature based on the radar backscatter coefficient (ALOS PALSAR) and brightness temperature (SMOS) data related to a tundra area on the Yamal peninsula were tested. As theoretical models, there were used the semi-empirical backscatter model proposed by Y. Oh et. al and the L-band Microwave Emission of the Biosphere (L-MEB) model proposed by J-P Wigneron et.al. An integral part of these models is a permittivity model of moist soil both thawed and frozen, which links backscatter coefficient and brightness temperature with moisture, temperature, and dry density of the soil as well as the wave frequencies used by the ALOS PALSAR and SMOS. The applied permittivity model was developed based on dielectric measurements conducted for the organic rich soil samples collected at the Vaskiny Dachi weather station located in the area of the radar backscatter and brightness observations. The retrieved temperatures were correlated with the ones measured at the weather station yielding the values of root-mean-square error and determination coefficient of 3.8°C and 0.80, respectively. © 2015 IEEE.

Аннотация: In the past, a maximum-entropy model was introduced and applied to the study of statistical scattering by chaotic cavities, when short paths may play an important role in the scattering process. In particular, the validity of the model was investigated in relation with the statistical properties of the conductance in open chaotic cavities. In this paper we investigate further the validity of the maximum-entropy model, by comparing the theoretical predictions with the results of computer simulations, in which the Schrodinger equation is solved numerically inside the cavity for one and two open channels in the leads; we analyze, in addition to the conductance, the zero-frequency limit of the shot-noise power spectrum. We also obtain theoretical results for the ensemble average of this last quantity, for the orthogonal and unitary cases of the circular ensemble and an arbitrary number of channels. Generally speaking, the agreement between theory and numerics is good. In some of the cavities that we study, short paths consist of whispering gallery modes, which were excluded in previous studies. These cavities turn out to be all the more interesting, as it is in relation with them that we found certain systematic discrepancies in the comparison with theory. We give evidence that it is the lack of stationarity inside the energy interval that is analyzed, and hence the lack of ergodicity-a property assumed in the maximum-entropy model-that gives rise to the discrepancies. Indeed, the agreement between theory and numerical simulations is improved when the energy interval is reduced to a point and the statistics is then collected over an ensemble obtained by varying the position of an obstacle inside the cavity. It thus appears that the maximum-entropy model is valid beyond the domain where it was originally derived. An understanding of this situation is still lacking at the present moment.

Аннотация: The ground and excited states of the pheromone molecules produced by xylophagous insects (the bark beetle Ips typographus L., the black fir sawyer beetle Monochamus urussovi Fisch., and the black pine sawyer M. galloprovincialis Oliv.) were modeled using a quantum chemical method utilizing DFT (density functional theory) with the B3LYP functional. The absorption wavelengths (energies) and dipole moments were calculated; the transitions of electrons from occupied to empty molecular orbitals were considered. The computed data were used to assess the stability of pheromone molecules exposed to environmental factors, such as solar radiation and humidity.

Аннотация: A multimode resonator is proposed, containing five resonant modes that are incorporated in the passband forming. The structure is based on a dielectric substrate suspended in a metallic case that allows solving problem of electromagnetic compatibility. Due to features of the resonator's structure, several higher modes do not excite that significantly improve the performance of the filter's stopband. The resonator advantages are proved on the ultra-wide bandpass filter (101%) with small overall size (0.11λ 0×0.06λ 0×0.03λ 0) and good stopband performance (first spurious band locates at 8 GHz, suppression is 80 dB).

Аннотация: Confident effect of five magnetic composite nanoparticles (FeP@Ag, FeP@Pd, CoP, NiP, Fe2O3@AГ) on growth of test bacteria colonies (Acinetobacter baumannii, Еscherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus) in five replicates each is considered. Reliable inhibitors of colonies of all five test bacteria were nanoparticles FeP@Ag. CoP nanoparticles are reliable inhibitors of growth of 4 test bacteria (except for test bacteria Escherichia сoli). NiP nanoparticles are reliable inhibitors of growth of 2 test bacteria: Escherichia сoli and Klebsiella pneumoniae. Bacteria Escherichia сoli were most sensitive to the effect of magnetic nanoparticles; and bacteria Pseudomonas aeruginosa and Staphylococcus aureus were most resistant to the effect of magnetic nanoparticles. The prospects of the method are in the possibility of multiple reuse of the magnetic particles with antimicrobial properties for bacterial decontamination of the studied sources of water and removal of magnetic nanoparticles from the treated liquids by electromagnet. The method can find use in water treatment facilities for household, Industrial and medical wastes.

Аннотация: This paper presents analysis of optical images of films obtained by evaporation (293 K) of a thin layer of low-concentrated (1% wt.) aqueous soot suspensions in a Petri dish. Suspensions of wood, fullerene and diamond-containing (after detonation synthesis) soot were prepared using hydrodynamic dispersion in a cavitation mixer with a wedge-shaped cavitator with the rotor's angular velocity of rotation being 10000 rpm. The components of the hydrodynamic dispersion process are turbulent micro-mixing and bubble cavitation. As a result of intense turbulence, carbon suspensions assumed properties of non-equilibrium systems. The images of an optical microscope revealed self-organized dissipative micron-sized structures in the dried films being present there in the form of chain, branched and ring-shaped cluster fractals of various dimensions that look very similar to nanotubes. The self-assembling effect was identified for all the types of suspensions under study. The EPR method was used to study the change in the electronic structure of soot resulting from the exposure to high temperatures and pressures that occur when the cavitation bubbles collapse (cavitational activation). The dynamics of changes in dissipative structures in the process of film drying was monitored.
