The deuteron beam vector polarization was obtained at the Nuclotron Internal Target Station using the proton-proton quasielastic scattering on the polyethylene target at the beam energies of 200, 500, 550, and 650 MeV/nucleon. The selection of useful events was performed using the time and amplitude information from scintillation counters. The asymmetry on hydrogen was obtained by the...
All attempts to include the original Dirac equation into the frameworks of the Principle of General Covariance and to obtain observable results have failed. It was shown that the Dirac field does not interact with the gravitational field (see for example:{S. Weinberg.} Gravitation and Cosmology: Principles and Applications of the General Theory of Relativity, Wiley, New York, 1972. 685...
We have derived the exact and approximate hadron transverse momentum distributions for the Fermi-Dirac, Bose-Einstein and Maxwell-Boltzmann statistics of particles in the framework of the Tsallis statistics with escort probabilities (the Tsallis-3 statistics). We have revealed that the classical approximate phenomenological Tsallis distribution in the framework of the Tsallis-3 statistics...
A Dual QCD formulation for SU(3) color gauge has been developed in terms of dual gauge potentials taking into account the local as well as topological structure of the color gauge group into its dynamics. For the purpose of examining the non perturbative characteristics of QCD, the dynamical configuration of the resulting dual QCD vacuum and its flux tube configuration have been examined. The...
Higher spin dynamics and multiparticle production in heavy ion collision processis, AdS/CFT correspondence, quarkonium potentials including finite temperature, finite density and entropic corrections considered.
The general formula that represents location of the
spin quantization axis of the meson-resonance $V$ in the inclusive reaction
$A+B\Longrightarrow V+X\Longrightarrow 1+2+X$ is suggested.
This formula determine the location of the spin
quantization axis of the particles 1,2 and $V$
via the cross sections of the subreactions $A+B\Longrightarrow V+X$ and $V\to 1+2$.
For this...
Non chiral spin texture gives rise to the topological Hall effects (THE). We analyze the topological property of one such spin texture, which was recently observed in van der Waals (vdW) magnet Fe3GeTe2. In this spin texture both the azimuthal and polar angle of the spin depend on the spatial coordinates. The Hamiltonian in strongly correlated regime with this spin texture for arbitrary large...
Frustration is a universal concept which describes a situation where several competing interactions are present, which takes place not only in physics but also biology. The compromise of such interactions may result in a completely exotic ground state. In frustrated magnets such competition can yield a loss of long-range magnetic order due to strong quantum fluctuations - a so-called quantum...
Advances in micro- and nano-technologies have led to the widespread use of spintronic magnetoresistive (MR) sensors for both recording and non-recording applications. Such ultramodern magnetoresistive sensors have high sensitivity of the detected ultra-weak fields, which meet the requirements of intelligent sensor applications in the fields of the Internet, mobile devices, space technology,...
Development of physics of ultracold atoms has opened unique possibility for realisation of R. Feynman’s idea: to use simple quantum systems with desiered properties (amenable quantitative description and modeling) to describe more complex systems and phenomena. Particularly, in solid state physics one can mention the modeling of matter phase-transition with the ultracold atom simulator...
