Discovering the Far East...’: Images of the Territory in the Works of V. K. Arsenyev

The article explores the works of the Far East explorer V.K. Arsenyev (1872–1930) with the purpose of using his works to find the representational potential of the region’s image. Using social constructivism as a methodology, we outline and analyze scientific and artistic types of constructing the Far East image and demonstrate the place each of these types occupies in Arsenyev’s works.     Keywords: regional image, constructivism, construct, visualization, Russian Far East, V.K.Arsenye

Soviet Anti-religious Film. “Sectarians” by Vladimir Korolevich (1930)

The article examines a unique phenomenon of Soviet cinema – the anti-religious film of the 1920s–1930s – a question insufficiently explored in humanitarian historiography so far. Being an organic part of the “cultural revolution”, on the one hand, anti-religious films of this period acted as an effective tool for the propaganda of the Soviet state in the fight against both the official church and manifestations of everyday religiosity. On the other hand, their creation was accompanied by detailed theoretical and methodological recommendations on the forms of interaction of party propagandists with the audience, and on the formats for the presentation of anti-religious attitudes. Based on previously unpublished archival materials, the authors bring to the fore one of the most indicative of such films titled “Sectarians” shoot by Vladimir Korolevich (Sovkino, 1930). The authors consider the film as a document of that time and analyze processes that ran parallel with one another in the Soviet culture and policy. Taking the film “Sectarians” as a case-study, the authors explore cinematic methods of constructing a negative image of sectarian organizations in the USSR and its broadcast to a wide audience in ideological way. The authors came to the conclusion that the Soviet anti-religious cinema, combining the techniques of avant-garde cinematography and scientific atheism, successfully fulfilled its propaganda mission. In this context, the film “Sectarians” is a valuable historical source, that represented the contradictory phenomena of its time and was aimed at the visual reconstruction of “Sovietness” as a new religion. © 2021, Amur State University.

Molecular dynamics study of cluster structure and properties of rotational waves in solid nanostructures

The paper reports a molecular dynamics analysis of rotary properties of a transformational wave generated due to compressive influence. Studies are performed in the time interval prior to the onset of elastic precursor reflection from the free boundary. It is shown that the leading front of a rotary wave coincides with the transformational wave front. The rotary wave velocity for copper is determined, being equal to 1300 m/s. The values of angular moment projections onto the coordinate axes in a plane perpendicular to wave propagation are found to be symmetrical, and their total sum equals zero

Uncertainty relations in curved spaces

Uncertainty relations for particle motion in curved spaces are discussed. The relations are shown to be topologically invariant. New coordinate system on a sphere appropriate to the problem is proposed. The case of a sphere is considered in details. The investigation can be of interest for string and brane theory, solid state physics (quantum wires) and quantum optics.Comment: published version; phase space structure discussion adde

Invariant variational principle for Hamiltonian mechanics

It is shown that the action for Hamiltonian equations of motion can be brought into invariant symplectic form. In other words, it can be formulated directly in terms of the symplectic structure $\omega$ without any need to choose some 1-form $\gamma$, such that $\omega= d \gamma$, which is not unique and does not even generally exist in a global sense.Comment: final version; to appear in J.Phys.A; 17 pages, 2 figure

Noether Symmetry Approach in "Cosmic Triad" Vector Field Scenario

To realize the accelerations in the early and late periods of our universe, we need to specify potentials for the dominant fields. In this paper, by using the Noether symmetry approach, we try to find suitable potentials in the "cosmic triad" vector field scenario. Because the equation of state parameter of dark energy has been constrained in the range of $-1.21\leq \omega\leq -0.89$ by observations, we derive the Noether conditions for the vector field in quintessence, phantom and quintom models, respectively. In the first two cases, constant potential solutions have been obtained. What is more, a fast decaying point-like solution with power-law potential is also found for the vector field in quintessence model. For the quintom case, we find an interesting constraint $\tilde{C}V_{p}'=-CV_{q}'$ on the field potentials, where $C$ and $\tilde{C}$ are constants related to the Noether symmetry.Comment: 15 pages, no figures, accepted by Classical and Quantum Gravity

Effective Theory Approach to the Spontaneous Breakdown of Lorentz Invariance

We generalize the coset construction of Callan, Coleman, Wess and Zumino to theories in which the Lorentz group is spontaneously broken down to one of its subgroups. This allows us to write down the most general low-energy effective Lagrangian in which Lorentz invariance is non-linearly realized, and to explore the consequences of broken Lorentz symmetry without having to make any assumptions about the mechanism that triggers the breaking. We carry out the construction both in flat space, in which the Lorentz group is a global spacetime symmetry, and in a generally covariant theory, in which the Lorentz group can be treated as a local internal symmetry. As an illustration of this formalism, we construct the most general effective field theory in which the rotation group remains unbroken, and show that the latter is just the Einstein-aether theory.Comment: 45 pages, no figures

Statistical Anisotropy from Anisotropic Inflation

We review an inflationary scenario with the anisotropic expansion rate. An anisotropic inflationary universe can be realized by a vector field coupled with an inflaton, which can be regarded as a counter example to the cosmic no-hair conjecture. We show generality of anisotropic inflation and derive a universal property. We formulate cosmological perturbation theory in anisotropic inflation. Using the formalism, we show anisotropic inflation gives rise to the statistical anisotropy in primordial fluctuations. We also explain a method to test anisotropic inflation using the cosmic microwave background radiation (CMB).Comment: 32 pages, 5 figures, invited review for CQG, published versio
