Liquid and crystal phase of dipolar fermions in two dimensions

The liquid and crystal phase of a single-component Fermi gas with dipolar interactions are investigated using quantum Monte Carlo methods in two spatial dimensions and at zero temperature. The dipoles are oriented by an external field perpendicular to the plane of motion, resulting in a purely repulsive 1/r^3 interaction. In the liquid phase we calculate the equation of state as a function of the interaction strength and other relevant properties characterizing the Fermi-liquid behavior: effective mass, discontinuity at the Fermi surface and pair correlation function. In the high density regime we calculate the equation of state of the Wigner crystal phase and the critical density of the liquid to solid first order phase transition. Close to the freezing density we also search for the existence of a stripe phase, but such a phase is never found to be energetically favorable.Comment: 5 pages, 5 figure

Dipolar Drag in Bilayer Harmonically Trapped Gases

We consider two separated pancake-shaped trapped gases interacting with a dipolar (either magnetic or electric) force. We study how the center of mass motion propagates from one cloud to the other as a consequence of the long-range nature of the interaction. The corresponding dynamics is fixed by the frequency difference between the in-phase and the out-of-phase center of mass modes of the two clouds, whose dependence on the dipolar interaction strength and the cloud separation is explicitly investigated. We discuss Fermi gases in the degenerate as well as in the classical limit and comment on the case of Bose-Einsten condensed gases.Comment: Submitted to EPJD, EuroQUAM special issue "Cold Quantum Matter - Achievements and Prospects

Personality determinants of manipulative behavior in the negotiation process

Negotiations are an inalienable component of human society in the modernworld, so studying those personal characteristics of negotiators that infl uencetheir choice of negotiating strategy, tactics, and style is relevant and signifi cant.Knowledge of the patterns of a partner’s choice of one strategy of behavior or anotherinfl uences on successful negotiation process and assists in achieving goals.We did research on the connections among level of anxiety, motivation to succeedand to avoid failure, and self-esteem to the level of Machiavellianism. This articlediscusses the personal characteristics that infl uence the choice of manipulativetactics of behavior in negotiations

New light-times curve of eclipsing binary AM Leo

We present 72 photoelectric and CCD times of minima of eclipsing binary AM Leo obtained mainly during 1996-2017 at Kourovka Astronomical Observatory of the Ural Federal University in Russia. We obtained new values of period of 50.5 years and eccentricity of 0.28 of the orbit of the eclipsing pair around the mass center of the system AM Leo with the third body. These results have been received taking into account the times of minima taken from literature and obtained from JD⊙ = 2435570 to JD⊙ = 2457835. © Konkoly Observatory Budapest, 2017.This work was supported in part by the Ministry of Education and Science (the basic part of the State assignment, RK no.

Development of Meat Snack Production Technology Using Herbal Ingredients

The relevance of the topic is obvious: snacks are very common in Russia as a product which is used to satisfy hunger on the go. But their market can be filled with both high and low-grade quality products. To be sure in the type of product, you need to know about raw materials, manufacturing technology, and methods of product identification. Moreover, modern people try to monitor their nutrition. This is evidenced by the development of such areas as functional nutrition. Therefore, snacks should not just be properly prepared, they should meet the standards of healthy nutrition. The aim of the article was to study the composition and properties of pumpkin oil, mustard cake and starter cultures of microorganisms, their influence on the quality indicators of meat snacks, the development of recipes and technologies of meat snacks with vegetable components, and the assessment of their quality, taking into account consumer preferences. Literature sources were analysed and patents were searched. This work will allow us to create competitive meat snacks that combine high consumer and functional properties, and recommend their implementation on an industrial scale at meat processing enterprises. Keywords: meat snacks, meat and vegetable products, herbal ingredients, mustard cake, pumpkin seed oil, starter crop
