Observation of polarization quantum noise of laser radiation in Rb vapor cell

We present experimental study of polarization quantum noise of laser radiation passed through optically think vapor of Rb87. We observe a step-like noise spectrum. We discuss various factor which may result in such noise spectrum and prevent observation of squeezing of quantum fluctuations predicted in Matsko et al. PRA 63, 043814 (2001).Comment: 4 pages, 5 figures. Translated from Russian by I. Novikov

Current trends in the development of Russian higher education in the context of the global economy digitalization

The analysis of current changes in the field of distance education, and, in particular, higher education among domestic and western universities is presented. The additional impact of the COVID-19 pandemic on the sharp increase in the popularity and use of online education in various segments of the educational process, starting from preschool and ending with corporate programs of companies is noted. The key advantages and disadvantages of online education are identified, as well as emerging risks for Russian Universities and the domestic economy when introducing distance learning

METHODS OF INCREASING THE LEVEL OF COMPETITIVENESS OF THE RUSSIAN FEDERATION IN THE WORLD THROUGH SUSTAINABLE DEVELOPMENT OF HUMAN CAPITAL

The methods of increasing the level of competitiveness of the Russian Federation in the world through sustainable development of human capital have been studied. The analysis of the most considerable indicators in the social and economic development of Russia and other leading economies in order to understand the current place and role of the Russian economy in the world society has been presented. Based on the analysis a number of reasons influencing on the further development of the Russian economy, taking into account the more active use of human capital in the global structure of the economy, has been revealed. The result of the study was to identify the weakest issues of the Russian economic structure including the fundamental difficulties in the development of human capital. At the end of the article, the main recommendations for fixing the identified problems have been given

Legal regulation of interreligious relations in the field of general education: the ratio of public and private interests

In article on the basis of the formal legal analysis of the national legal system and the international jurisprudence the key principles of state legal regulation of the confessional relations in the sphere of the general education are distinguished; the need of their addition and unification at the national level for the purpose of providing the balanced ratio of public and private interests in the context of providing the integrated rights and personal freedoms is demonstrate

Diffusion-induced Ramsey narrowing

A novel form of Ramsey narrowing is identified and characterized. For long-lived coherent atomic states coupled by laser fields, the diffusion of atoms in-and-out of the laser beam induces a spectral narrowing of the atomic resonance lineshape. Illustrative experiments and an intuitive analytical model are presented for this diffusion-induced Ramsey narrowing, which occurs commonly in optically-interrogated systems.Comment: 4 pages, 8 figure

Optimal control of light pulse storage and retrieval

We demonstrate experimentally a procedure to obtain the maximum efficiency for the storage and retrieval of light pulses in atomic media. The procedure uses time reversal to obtain optimal input signal pulse-shapes. Experimental results in warm Rb vapor are in good agreement with theoretical predictions and demonstrate a substantial improvement of efficiency. This optimization procedure is applicable to a wide range of systems.Comment: 5 pages, 4 figure

The impact of government regulation on the Russian competitiveness within global “green” economy in conditions of sanctions

The aim of this paper is the study of the impact of state tax regulation on the competitiveness level of the Russian economy taking into account the development of “green” initiatives in the current conditions of sanctions pressure. This research includes the analysis of current positions of key countries promoting the initiative of “green” economy at the global level, and key beneficiaries of implemented mechanism are considered. Additionally, the situation in the Russian economy has been outlined within the global “green” economy with suggestions of the most efficient position for the national economy within the current situation. Moreover, this research includes the analysis of “green” economy concept development, its promotion and implementation by countries with the usage of different indicators for results measuring of economies by global “green” rankings

Agreements in criminal processes: problems of application and development

In this paper, institutions of agreements (mediation) in criminal proceedings in various states were investigated regarding the history of their occurrence and development. The aspects under the study included features related to the use of institutions of agreement in individual countries (USA, Canada, Germany, Russia, Moldova, etc.); the regulatory framework of these countries, statistics on the use of institutions of agreements (mediation), as well as programs used as mediatio

Limits of using the results of polygraph testing in criminal procedure

An offer for restrictions, concerning the limits of use of polygraph testing results as orientation information at pre-trial stages of criminal proceedings, was made in this articl
