Multiparticle Correlations at LEP1

Bidding farewell to the LEP accelerator, we acknowledge that an essential part of its legacy is the immense amount of data collected during 5 years of the LEP1 stage, at the Z peak. This set of data allows for detailed studies of many phenomena, and particularly, of the final state interactions between hadrons. Presented here is a review of the most recent analyses in this area.Comment: 6 pp, 4 figs, talk presented at the XXX International Symposium on Multiparticle Dynamics, October 9-15, 2000, Tihany, Hungar

Re-employment Probabilities and Wage Offer Function for Russian Labor Market

This research addresses labor market transformation in Russia. It elaborates on the theory of job search and focuses on the following issues: (1) evaluation of the re-employment probabilities (hazard rates) for different socio-economic groups; and (2) estimation of wage offer distribution for the transforming labor market. We use data from Phase II of the Russia Longitudinal Monitoring Survey (RLMS) to estimate the employment and wage offer functions for Russian workers who found a job after having been unemployed. We take into account the effectiveness of search strategies used and correct for truncation in wage offers. The binomial logit-OLS estimation method with sample selection bias correction on pooled data from Rounds 5-9 of RLMS is used. The factors considered are sex, education, experience, sector of employment and search methods’ success rate, which are hypothesized to capture the main determinants of job search behavior. The results show that individual characteristics, as well as the search method used, play a decisive role in the re-employment prospects of the unemployed. The private sector employment level is estimated to have the most powerful positive effect on the wage offer function. Russian women are less likely than men to find a job after being unemployed, and wage offers for women are estimated to be lower than for men.http://deepblue.lib.umich.edu/bitstream/2027.42/39932/3/wp547.pd

Spin polarized electrons produced by strong field ionization

We show that ionization of noble gas atoms by strong infrared circularly polarized laser field under standard exerimental conditions can yield electrons with up to 100% spin polarization in energy resolved measurements. Spin polarization arises due to the interplay of the electron-core entanglement and the sensitivity of ionization in circularly polarized fields to the sense of electron rotation in the initial state.Comment: 10 pages, 2 figure

Conflicting Tendencies in the Development of Scientific and Technical Language Varieties: Metaphorization vs. Standardization

The present paper discusses relations between meaning and context as an interactive process that promotes cognition and communication, both intralingual and interlingual. The article also studies two evident conflicting tendencies in the development of technical language: metaphorization and standardization. Metaphorical meaning extension is characteristic of technical vocabulary in all discourse domains. At the same time, contemporary development of corpus linguistics facilitates standardization of terms. Taking into account pragmatic aspects of the text environment, i.e. referential, situational, cultural and social contexts, language users can interpret the meaning of new terms, establish relations and interconnections between terms and concepts within a text, domain and entire scientific and technical discourse. In the present article, observations on the nature and application of contemporary technical terminology are made on the basis of extensive empirical research

Nonadiabatic tunneling in circularly polarized laser fields: Derivation of formulas

We provide detailed analysis of strong field ionization of degenerate valence p orbitals by circularly polarized fields. Our analytical approach is conceptually equivalent to the Perelomov, Popov, and Terent'ev (PPT) theory and is virtually exact for short range potentials. After benchmarking our results against the PPT theory for s orbitals, we obtain the results for p orbitals. We also show that, as long as the dipole approximation is valid, both the PPT method and our results are gauge invariant, in contrast with widely used strong field approximation (SFA). Our main result, which has already been briefly outlined in [I. Barth and O. Smirnova, Phys. Rev. A 84, 063415 (2011)], is that strong field ionization preferentially removes electrons counter-rotating to the circularly polarized laser field. The result is illustrated using the example of Kr atom. Strong, up to one order of magnitude, sensitivity of strong field ionization to the sense of electron rotation in the initial state is one of the key signatures of non-adiabatic regime of strong field ionization.Comment: 42 pages, 3 figure

Second-harmonic generation in subwavelength graphene waveguides

We suggest a novel approach for generating second-harmonic radiation in subwavelength graphene waveguides. We demonstrate that quadratic phase matching between the plasmonic guided modes of different symmetries can be achieved in a planar double-layer geometry when conductivity of one of the layers becomes spatially modulated. We predict theoretically that, owing to graphene nonlocal conductivity, the second-order nonlinear processes can be actualized for interacting plasmonic modes with an effective grating coupler to allow external pumping of the structure and output of the radiation at the double frequency.Comment: 5 pages, 3 figure
