A 4-Component Dirac Theory of Ionization of Hydrogen Molecular Ion in a Super-Intense Laser Field
In this paper a 4-component Dirac theory of ionization of hydrogen molecular
ion in a super-intense laser field is developed. Simple analytic expressions
for the spin specific as well as the total ionization currents emitted from the
ground state of the ion are derived. The results are given for all polarization
and finite propagation vectors of the field. They apply for inner-shell
ionization of analogous heavier molecular ions as well. The presence of
molecular two-slit interference effect, first found in the non-relativistic
case, and the spin-flip ionization current, and an asymmetry of the up- and
down-spin currents similar to that predicted in the atomic case, are found also
to hold for the present relativistic molecular ionic case. Finally, the
possibility of controlling the dominant spin currents by selecting the
handedness of a circularly polarized incident laser field is pointed out.Comment: 7 pages, no figure
Interplay of polarization geometry and rotational dynamics in high harmonic generation from coherently rotating linear molecule
Recent reports on intense-field pump-probe experiments for high harmonic
generation from coherently rotating linear molecules, have revealed remarkable
characteristic effects of the simultaneous variation of the polarization
geometry and the time delay on the high harmonic signals. We analyze the
effects and give a unified theoretical account of the experimental observationsComment: 4 pages, 5 figure
Pengaruh Assurance Sustainability Report Terhadap Market Value Perusahaan Yang Terdaftar Di Bei Pada Tahun 2011-2013
Currently Indonesian companies began to publish sustainability report as a corporate responsibility to the environment. To increase the credibility of the sustainability report, the company did assurance, but not much research the topic of assurance. This study aimed to analyze the effect of assurance on the sustainability report to the market value of the company. This study used independent assurance, size, leverage, ROA, the type of industry to measure the market value of the company.This study used secondary data documentation, they were sustainability report and annual report companies that listed on the Stock Exchange in 2011-2013. The sampling method used in this research is purposive sampling with some requirements. The number of samples obtained from these criteria were 36 companies with a total of 108 samples. in This study used multiple linear regression to test the hypothesis.The results showed that the assurance negative and not significant effect to the market value of the company. Other variables such as the size (the size of the company), leverage, and the type of industry also did not have a significant effect. Only ROA which had a positive and significant effect to the market value of the company
Multiphoton excitations in vibrational rotational states of diatomic molecules in intense electromagnetic field
A theory is presented and a calculational procedure is outlined for evaluating transition amplitudes of multiphoton excitations of vibrational-rotational levels in diatomic molecules. This theory can be utilized in studying behavior of molecules in intense electromagnetic fields
