    The coupling of the X1Σ+^{1}\Sigma ^{+} and a3Σ+^{3}\Sigma ^{+} states of KRb

    Full text link
    A comprehensive study of the electronic states at the 4s+5s asymptote in KRb is presented. Abundant spectroscopic data on the \astate state were collected by Fourier-transform spectroscopy which allow to determine an accurate experimental potential energy curve up to 14.8 \AA . The existing data set (C. Amiot et al. J. Chem. Phys. 112, 7068 (2000)) on the ground state \Xstate was extended by several additional levels lying close to the atomic asymptote. In a coupled channels fitting routine complete molecular potentials for both electronic states were fitted. Along with the line frequencies of the molecular transitions, recently published positions of Feshbach resonances in 40^{40}K and 87^{87}Rb mixtures (F. Ferlaino et al. Phys. Rev. A 74, 039903 (2006)) were included in the fit. This makes the derived potential curves capable for an accurate description of observed cold collision features so far. Predictions of scattering lengths and Feshbach resonances in other isotopic combinations are reported.Comment: 14 pages, 5 figure

    The potential of the ground state of NaRb

    Full text link
    The X1Σ+^{1}\Sigma ^{+} state of NaRb was studied by Fourier transform spectroscopy. An accurate potential energy curve was derived from more than 8800 transitions in isotopomers 23^{23}Na85^{85}Rb and 23^{23}Na87^{87}Rb. This potential reproduces the experimental observations within their uncertainties of 0.003 \rcm to 0.007 \rcm. The outer classical turning point of the last observed energy level (v=76v''=76, J=27J''=27) lies at 12.4\approx 12.4 \AA, leading to a energy of 4.5 \rcm below the ground state asymptote.Comment: 8 pages, 6 figures and 2 table

    Formation of ultracold RbCs molecules by photoassociation

    Full text link
    The formation of ultracold metastable RbCs molecules is observed in a double species magneto-optical trap through photoassociation below the ^85Rb(5S_1/2)+^133Cs(6P_3/2) dissociation limit followed by spontaneous emission. The molecules are detected by resonance enhanced two-photon ionization. Using accurate quantum chemistry calculations of the potential energy curves and transition dipole moment, we interpret the observed photoassociation process as occurring at short internuclear distance, in contrast with most previous cold atom photoassociation studies. The vibrational levels excited by photoassociation belong to the 5th 0^+ or the 4th 0^- electronic states correlated to the Rb(5P_1/2,3/2)+Cs(6S_1/2) dissociation limit. The computed vibrational distribution of the produced molecules shows that they are stabilized in deeply bound vibrational states of the lowest triplet state. We also predict that a noticeable fraction of molecules is produced in the lowest level of the electronic ground state

    Dark resonances for ground state transfer of molecular quantum gases

    Full text link
    One possible way to produce ultracold, high-phase-space-density quantum gases of molecules in the rovibronic ground state is given by molecule association from quantum-degenerate atomic gases on a Feshbach resonance and subsequent coherent optical multi-photon transfer into the rovibronic ground state. In ultracold samples of Cs_2 molecules, we observe two-photon dark resonances that connect the intermediate rovibrational level |v=73,J=2> with the rovibrational ground state |v=0,J=0> of the singlet X1Σg+X^1\Sigma_g^+ ground state potential. For precise dark resonance spectroscopy we exploit the fact that it is possible to efficiently populate the level |v=73,J=2> by two-photon transfer from the dissociation threshold with the stimulated Raman adiabatic passage (STIRAP) technique. We find that at least one of the two-photon resonances is sufficiently strong to allow future implementation of coherent STIRAP transfer of a molecular quantum gas to the rovibrational ground state |v=0,J=0>.Comment: 7 pages, 4 figure

    We report the calculation of the interspecies scattering length for the sodium-rubidium (Na-Rb) system. We present improved hybrid potentials for the singlet X1Σ+X^1\Sigma^+ and triplet a3Σ+a^3\Sigma^+ ground states of the NaRb molecule, and calculate the singlet and triplet scattering lengths asa_{s} and ata_{t} for the isotopomers 23^{23}Na87^{87}Rb and 23^{23}Na85^{85}Rb. Using these values, we assess the prospects for producing a stable two-species Bose-Einstein condensate in the Na-Rb system.Comment: v2: report correct units in Table captions, fix error in conclusions for 23^{23}Na85^{85}Rb TBEC. Otherwise, more concise presentation, typos fixed. 6 pages, 1 figur

    The Idea of Education: Development or Service Delivery?

    Get PDF
    Introduction. In recent years, the debates over the education crisis, its essence and the role in the development of a person and culture in general have underlined the need to scientifically define the concept of modern education. The present article is debatable and theoretical; therefore, it explores the idea of education from the perspective of the current trend – the classification of education as a service sector. The aim of the article is to scientifically justify irrelevance of the ideas of education as a “commercial service” through the discussion of consequences of such an interpretation. Methodology and research methods. The research methodology is based on a meta-systemic approach, which allows us to consider education as the system in a number of other social institutes and structures and as an element of a larger system. The logical-semantic analysis, hermeneutic method and synthesis of the views among the representatives in the filed of the humanities were used to study the phenomenon of “educational services”. To determine own position, the authors of the present article used the procedure of separating “social construction paradigms” (as a set of principles of knowledge and transformation of social reality), which make it possible to give diverse definitions of society and to introduce the concepts of the essence and the role of education. Results. The concept of “educational services” is analysed as a speech template, a way of thinking, a legal concept, a call to changing social practice and a probable project. The authors reveal a conceptual, semantic substitution, which negatively affects the result of the educational process: the meaning of profit has taken the place of the sense of personal development and social long-term viability and development of society. It is demonstrated that this semantic substitution is a natural consequence of the market laws, going beyond the social control, in particular, their semi-legitimate expansion into the sphere of education, which is a significant public good. Scientific novelty. It is proved that an established expression “educational services” in modern discourse contributes to destructive transformations of the citizens’ mentality and social space. The concepts of “service” and “education” are characterised according to a set of the following criteria: a subject of activity, its nature, a recipient role, specificity of the methods of activity, its result (or its goal) and quality assessment. It is concluded that the sectors of service and education can be characterised as joint constructive human activities, but they are fundamentally different activities. Practical significance. The obtained results could be applied to provide purposeful adjustment processes for conceptual management of the education sector.Введение. Развернувшийся в последние годы дискурс о кризисе образования и обострившийся спор о его сущности и роли в развитии человека и культуры в целом обусловили необходимость научного определения смысла современного образования. В дискуссионной и теоретической по характеру статье данный вопрос исследуется в ракурсе актуальной тенденции отнесения образования к сфере услуг. Цель работы состояла в научном обосновании нерелевантности представлений об образовании как о «коммерческой услуге» и обсуждении последствий подобной интерпретации. Методология и методики. Исследование выполнялось на базе метасистемного подхода, позволяющего рассматривать образование как систему в ряду других социальных институтов и структур и как элемент системы большего порядка. Изучение феномена «образовательные услуги» проводилось посредством логико-смыслового анализа, герменевтического метода и синтеза мнений представителей разных гуманитарных наук. Для аргументации собственной позиции авторы использовали процедуру разделения «парадигм социоконструирования» (как совокупности принципов познания и преобразования социальной реальности), из которых логически выводятся разные дефиниции общества, определения сущности и роли образования. Результаты. Концепт «образовательные услуги» проанализирован как речевой шаблон, способ мышления, юридическое понятие, призыв к изменению социальной практики и как вероятный проект. Выявлена негативно влияющая на результаты образования концептуальная, смысловая подмена: смысл извлечения прибыли занял место смысла совершенствования личности и обеспечения долгосрочной жизнеспособности и развития всего общества. Показано, что данная подмена – закономерное следствие выхода рыночных законов за рамки социального контроля, в частности их полулегитимного распространения на сферу образования, являющегося общественно значимым благом. Научная новизна. Доказывается, что закрепившееся в современном дискурсе выражение «образовательные услуги» способствует деструктивным трансформациям менталитета граждан и социального пространства. Услуга и образование охарактеризованы по комплексу критериев: предмет деятельности, ее характер, роль акцептора продукта деятельности, особенности методов деятельности, результат (цель) деятельности и оценка качества. Сделан вывод о том, что сфера услуг и образование – это области совместной конструктивной деятельности людей, имеющие принципиальные различия. Практическая значимость. Полученные результаты позволяют целенаправленно корректировать процессы концептуального управления сферой образования.The present research was carried out with the financial support of the Russian Foundation for Basic Research in the framework of the research project No. 19–013–00373 A “Academic Mobility of Students with Disabilities in the Context of the Transformation of Higher Education”.Исследование выполнено при финансовой поддержке РФФИ в рамках научного проекта № 19–013–00373 А «Академическая мобильность студентов с ограниченными возможностями здоровья и инвалидностью в условиях трансформации высшего образования»

    Hydrogen-like nitrogen radio line from hot interstellar and warm-hot intergalactic gas

    Full text link
    Hyperfine structure lines of highly-charged ions may open a new window in observations of hot rarefied astrophysical plasmas. In this paper we discuss spectral lines of isotopes and ions abundant at temperatures 10^5-10^7 K, characteristic for warm-hot intergalactic medium, hot interstellar medium, starburst galaxies, their superwinds and young supernova remnants. Observations of these lines will allow to study bulk and turbulent motions of the observed target and will broaden the information about the gas ionization state, chemical and isotopic composition. The most prospective is the line of the major nitrogen isotope having wavelength 5.65 mm (Sunyaev and Churazov 1084). Wavelength of this line is well-suited for observation of objects at z=0.15-0.6 when it is redshifted to 6.5-9 mm spectral band widely-used in ground-based radio observations, and, for example, for z>=1.3, when the line can be observed in 1.3 cm band and at lower frequencies. Modern and future radio telescopes and interferometers are able to observe the absorption by 14-N VII in the warm-hot intergalactic medium at redshifts above z=0.15 in spectra of brightest mm-band sources. Sub-millimeter emission lines of several most abundant isotopes having hyperfine splitting might also be detected in spectra of young supernova remnants.Comment: 12 pages, 5 figures, accepted by Astronomy Letters; v3: details added; error fixe

    Progress on researches in the field of molecules at cold and ultracold temperatures is reported in this review. It covers extensively the experimental methods to produce, detect and characterize cold and ultracold molecules including association of ultracold atoms, deceleration by external fields and kinematic cooling. Confinement of molecules in different kinds of traps is also discussed. The basic theoretical issues related to the knowledge of the molecular structure, the atom-molecule and molecule-molecule mutual interactions, and to their possible manipulation and control with external fields, are reviewed. A short discussion on the broad area of applications completes the review.Comment: to appear in Reports on Progress in Physic

    Athlome Project Consortium: a concerted effort to discover genomic and other "omic" markers of athletic performance.

    Get PDF
    Despite numerous attempts to discover genetic variants associated with elite athletic performance, injury predisposition, and elite/world-class athletic status, there has been limited progress to date. Past reliance on candidate gene studies predominantly focusing on genotyping a limited number of single nucleotide polymorphisms or the insertion/deletion variants in small, often heterogeneous cohorts (i.e., made up of athletes of quite different sport specialties) have not generated the kind of results that could offer solid opportunities to bridge the gap between basic research in exercise sciences and deliverables in biomedicine. A retrospective view of genetic association studies with complex disease traits indicates that transition to hypothesis-free genome-wide approaches will be more fruitful. In studies of complex disease, it is well recognized that the magnitude of genetic association is often smaller than initially anticipated, and, as such, large sample sizes are required to identify the gene effects robustly. A symposium was held in Athens and on the Greek island of Santorini from 14-17 May 2015 to review the main findings in exercise genetics and genomics and to explore promising trends and possibilities. The symposium also offered a forum for the development of a position stand (the Santorini Declaration). Among the participants, many were involved in ongoing collaborative studies (e.g., ELITE, GAMES, Gene SMART, GENESIS, and POWERGENE). A consensus emerged among participants that it would be advantageous to bring together all current studies and those recently launched into one new large collaborative initiative, which was subsequently named the Athlome Project Consortium
