Coherent Control of Photoelectron Wavepacket Angular Interferograms

Coherent control over photoelectron wavepackets, via the use of polarization-shaped laser pulses, can be understood as a time and polarization-multiplexed process. In this work, we investigate this multiplexing via computation of the observable photoelectron angular interferograms resulting from multi-photon atomic ionization with polarization-shaped laser pulses. We consider the polarization sensitivity of both the instantaneous and cumulative continuum wavefunction; the nature of the coherent control over the resultant photoelectron interferogram is thus explored in detail. Based on this understanding, the use of coherent control with polarization-shaped pulses as a methodology for a highly multiplexed coherent quantum metrology is also investigated, and defined in terms of the information content of the observable.Comment: 9 pages, 5 figure

The positive impact of irrational beliefs?: A mutual connection with justice sensitivity

Rational-Emotive-Behavior Therapy (REBT, Ellis, 1962, 1994) postulates that irrational thinking implies demanding thoughts about punishing people for their evil activities. Hence, irrational thinking should be associated with increased individual sensitivity concerning unfair social events. Results of our study (N = 108) confirm this hypothesized correlation between Irrationality and Justice Sensitivity. Notably, the strongest correlation was found between low frustration tolerance, a subdimension of irrationality, and justice sensitivity from the perspective of a victim. This indicates that easily frustrated individuals are particularly prone to suffer when being treated unfairly and are, therefore, eminently susceptive to justice sensitivity

Femtosecond real-time probing of reactions. XI. The elementary OClO fragmentation

Femtosecond reaction dynamics of OClO in a supersonic molecular beam are reported. The system is excited to the A 2A2 state with a femtosecond pulse, covering a range of excitation in the symmetric stretch between v1=17 to v1=11 (308–352 nm). A time-delayed femtosecond probe pulse ionizes the OClO, and OClO + is detected. This ion has not been observed in previous experiments because of its ultrafast fragmentation. Transients are reported for the mass of the parent OClO as well as the mass of the ClO. Apparent biexponential decays are observed and related to the fragmentation dynamics: OClO+hnu-->(OClO)[double-dagger]*-->ClO+O -->Cl+O2 . Clusters of OClO with water (OClO)n (H2O)m with n from 1 to 3 and m from 0 to 3 are also observed. The dynamics of the fragmentation reveal the nuclear motions and the electronic coupling between surfaces. The time scale for bond breakage is in the range of 300–500 fs, depending on v1; surface crossing to form new intermediates is a pathway for the two channels of fragmentation: ClO+O (primary) and Cl+O2 (minor). Comparisons with results of ab initio calculations are made

International Cooperation on Trade and Labor Issues

The relationship between the labor market and international trade is a broad and complex subject that has been the focus of significant attention in recent years. Discussion and analysis in this area has covered a number of discrete issues, including the effect of shifting trade patterns on employment levels and earnings in domestic markets, the impact of wage levels and labor legislation on the location of production facilities, and the positive and negative aspects of the cross-border movement of workers, among others. The continuing importance of labor issues within the larger trade debate is highlighted by the inclusion of measures relating to labor standards and/or the cross-border movement of workers in recent bilateral and multilateral trade agreements such as the North American Free Trade Agreement (NAFTA), the General Agreement on Trade in Services (GATS), and the U.S.–Oman Free Trade Agreement. This paper aims to provide background for future work on trade-related labor issues by describing how labor issues such as internationally recognized labor standards and the cross-border movement of workers have been addressed by international organizations, as well as in U.S. trade legislation and recent trade agreements
