Isovector Pair Correlations of Nucleons in Atomic Nuclei: Microscopic Approach, Boson Representation and Collective Model
(rus, 446.881)

Pair correlations of nucleons in atomic nuclei are analyzed in the framework of the microscopic nuclear model with isovector pairing. The method of the boson representations of the fermion operators is used for this aim. The method gives a possibility to determine a collective mode of the pair excitations without restricting a single particle basis. Using this method it is possible to consider fluctuations of the nonsuperfluid nuclear matter, phase transition from nonsuperfluid to superfluid system and strong pair correlations. The consideration is illustrated by the results of calculations obtained for nuclei around 56Ni.

Spinor Field Nonlinearity and Space-Time Geometry
(rus, 1.115.807)

Within the scope of Bianchi type-VI, VI0, V, III, I, LRSBI and FRW cosmological models we have studied the role of nonlinear spinor field in the evolution of the Universe and the field itself. It was found that due to the presence of non-trivial non-diagonal components of the energy-momentum tensor of the spinor field in the anisotropic space-time, there occur some severe restrictions both on the metric functions and on the components of the spinor field. In this report we have considered a polynomial nonlinearity which is a function of invariants constructed from the bilinear spinor forms. It is found that in case of a Bianchi type-VI space-time, depending on the sign of self-coupling constants, the model allows either late time acceleration or oscillatory mode of evolution. In case of a Bianchi type-VI0 space-time due to the specific behavior of the spinor field we have two different scenarios. In one case the invariants constructed from bilinear spinor forms become trivial, thus giving rise to a massless and linear spinor field Lagrangian. This case is equivalent to the vacuum solution of the Bianchi type-VI0 space-time. The second case allows non-vanishing massive and nonlinear terms, and depending on the sign of coupling constants, gives rise to accelerating mode of expansion or the one that after obtaining some maximum value contracts and ends in big crunch, consequently generating space-time singularity. In case of a Bianchi type-V model there occur two possibilities. In one case we found that the metric functions are similar to each other. In this case the Universe expands with acceleration if the self-coupling constant is taken to be a positive one, whereas a negative coupling constant gives rise to a cyclic or periodic solution. In the second case the spinor mass and the spinor field nonlinearity vanish and the Universe expands linearly in time. In case of a Bianchi type-III model the space-time remains locally rotationally symmetric all the time, though the isotropy of space-time can be attained for a large proportionality constant. As far as evolution is concerned, depending on the sign of coupling constant the model allows both accelerated and oscillatory mode of expansion. A negative coupling constant leads to an oscillatory mode of expansion, whereas a positive coupling constant generates expanding Universe with late time acceleration. Both deceleration parameter and EoS parameter in this case vary with time and are in agreement with modern concept of space-time evolution. In case of a Bianchi type-I space-time the non-diagonal components lead to three different possibilities. In case of a full BI space-time we find that the spinor field nonlinearity and the massive term vanish, hence the spinor field Lagrangian becomes massless and linear. In two other cases the space-time evolves into either LRSBI or FRW Universe. If we consider a locally rotationally symmetric BI (LRSBI) model, neither the mass term nor the spinor field nonlinearity vanishes. In this case depending on the sign of coupling constant we have either late time accelerated mode of expansion or oscillatory mode of evolution. In this case for an expanding Universe we have asymptotical isotropization. Finally, in case of a RW model neither the mass term nor the spinor field nonlinearity vanishes. Like in LRSBI case we have either late time acceleration or cyclic mode of evolution. These findings allow us to conclude that the spinor field is very sensitive to the gravitational one.

Determination of the Fundamental Physical Constants: The Base of the New “Quantum” SI Units
(rus, 1.093.194)

The metric system of units has appeared as a system of units, designed for macroscopic measurements (of the laboratory scale). Progress in determination of the values of the quantum constants (such as the Planck constant) in SI units proves the increased possibilities of high-precision measurements of both microscopic and macroscopic quantities in the same units. In the meantime, the relative microscopic measurements (such as comparison of the frequencies of atomic transitions or comparison of atomic masses) are often significantly more accurate than the relative measurements of macroscopic values. That motivates a strategy of defining units in the microscopic phenomena and their further use in measurements of the laboratory scale, which play a crucial role in practical metrological applications, determined by the everyday life and technologies. CODATA task group on fundamental constants regularly performs an overall analysis of the precision world data (known as least square adjustment) and publishes their recommended values. The most recent evaluation of this sort was based on the data published by the end of 2014 and here we review the related data and results. The accuracy in determination of the Boltzmann constant has increased and the consistency of the data on the determination of the Planck constant has improved, while these two constants are going to be the base of the new definition of the kelvin and kilogram in the near future. The controversy in determination of the Rydberg constant and the proton charge radius remains. Accuracy of the determination of the fine structure constant and relative atomic weight of the electron has been improved. A detailed review of the state of the art in precision determination of the values of fundamental constants is presented. The mathematical procedure of the adjustment is considered as well as the new data and the results. Limitations due to macroscopic properties of material standards (such as the international prototype of the kilogram) and the isotopic composition of substances involved in precision studies in general (such as the standard measures for the triple point of water) and, in particular, in the determination of fundamental constants are treated. The perspectives of the introduction of the new quantum units, which will be free of the mentioned problems, are discussed. Many physicists feel no sympathy to the International System of Units (SI), suggesting that it does not properly reflect the character of physical laws. There are in fact three parallel systems, namely, the system of quantities, system of their units and the related standards. Definition of the units, and in particular of the SI units, at the first place reflects our ability to perform precision measurements of physical values under certain conditions, and in particular to build the appropriate standards. This requirement is not related to the beauty of fundamental natural laws. The determination of the fundamental constants is one of the areas where we accumulate such an experience.

Multilayer Semiconductor Spectrometers of Charged Particles for Accelerator Experiments
(rus, 3.254.893)

The current state of development in the field of multi-layer semiconductor systems (SCD telescopes) is presented. It has been shown that these telescopes make it possible to have a high energy resolution in a large dynamic range (from several to hundreds of MeV) and identification of detecting charged particles in a wide range of masses (from pions to multiply charged nuclear fragments). The manufacturing methods of detectors from silicon and HP germanium for SCD telescopes are described. The methods of measuring the characteristics of the detectors and their impact on the energy resolution of the telescope spectrometers and the quality of the experimental data are presented. Considerable attention is paid to the use of multilayer semiconductor devices in the experimental studies on accelerators of PNPI (Gatchina), LANL (Los Alamos) and CELSIUS (Uppsala).
