Hawking radiation of scalar particles of Kerr-Newman-de Sitter XY (KNdSXY) black holes is studied by using complex analytical continuation (CAC) technique. We derive the surface gravity κ_{h},κ_{c} and Hawking temperature T_{b},T_{c} of the event horizons r_{+},r_{++}. All of them are proportional to (|A|)^{1/2}, where A is an indefinite multiple of KNdSXY metric.

In this paper, analytic expressions of Gaussian curvature, Euler's characteristic and area of Schwarzschild surface for an accelerating particle are given. The effect of acceleration on the equatorial and polar circumferences is analyzed. The problem of embedding this surface into Euclidean 3-space is also examined.

The critical behaviors of bond percolation on a family of Sierpinski carpets (SCs) are studied. We distinguish two sorts of bonds and assign them to two kinds of occupation probabilities. We develop the usual choice of cell on translationally invariant lattices and choose suitable cells to cover the fractal lattice. On this basis we construct a new real-space renormalization group (RG) transformation scheme and use it to solve the percolation problems. Phase transitions of percolation on such fractals with infinite order of ramification are found at non-trivial bond occupation probabilities. The percolation threshold values, correlation length exponents ν, and the RG flow diagrams are obtained. The flow diagrams are remarkably similar to those of Ising model and Potts model. This agrees with the correspondence between the pure bond percolation and Potts model.

Zeeman modulation-magnetic rotation spectroscopic (ZM-MRS) technique is provided with not only high sensitivity and high signal-to-noise ratio, but also apparent phase character for studying molecular spectrum. It is quite helpful for assigning some complex molecular rotational spectra. As an example, the ZM-MRS spectra of NO_{2} molecule was measured in the region between 16838cm^{-1} and 16860cm^{-1} with high resolution. The semi-classical magnetic rotation theory was used to explain the spectral feature and its phase relation with transition quantum number. It is in agreement with the experimental results. Finally, by using matrix diagonalization of effective Hamiltonian, the ZM-MRS spectra of NO_{2} molecule were analyzed and a reasonable assignment was obtained.

In this paper, we have calculated and analyzed theoretically and consistently the absorption spectra, the ZFS and EPR parameters of the ground state, the Schottky low-temperature heat capacity, and the paramagnetic susceptibility of Ni(pz)_{4}Cl_{2} (Dichlorotetrapyrazolenickel) complex by using d^{8}[(1-C_{2})D^{*}_{4h}+C_{2}D^{*}_{2h}] complete configuration mixing unified crystal field theory. The theoretical results agree with the experimental observation very well. We can give a complete and reasonable theoretical interpretation of the optical, thermal and magnetic properties of Ni(pz)_{4}Cl_{2}.

We present a method to generate entangled Fock states of two nonlocal cavity modes with different frequencies. We send an atom with three levels g,e, and f across two cavities. The atomic transition frequency between level g and e is resonant with the first cavity frequency, while the atomic transition frequency between level g and f is resonant with the second cavity frequency. The detection of the atomic state leaves the pure field in an entangled Fock state.

PHYSICS OF GASES, PLASMAS, AND ELECTRIC DISCHARGES

Theoretical and experimental studies of the angular distributions of scattered laser light in laser-Au-plate-target coupling are reported. A simple model that describes three-dimensional plasmas and scattered laser light is presented. The approximate shape of critical density surface has been given and the three-dimensional laser ray tracing is applied in the model. The theoretical results of the model are consistent with the experimental data for the scattered laser light in the polar angle range of 25o to 145o from the laser beam.

Electron cyclotron current start-up as a scheme to initiate ohmic discharges has been investigated with two circuits of open and shorted primary windings of transformer. The experimental results indicate that we can achieve the saving of equivalent flux and the reduction of starting voltage in the initial phase for the two circuits in fundamental frequency resonance region.

CONDENSED MATTER: ELECTRONIC STRUCTURE, ELECTRICAL, MAGNETIC, AND OPTICAL PROPERTIES

The effects of Ca^{2+} ions on the structure and dielectric and pyroelectric characteristics of PbTiO_{3} polycrystals were investigated. With increasing content of Ca, a decrease in tetragonal axial ratio (c/a) was observed as a consequence of shrinkage of the lattice parameter c. The dielectric constant and pyroelectric coefficient increase and Curie temperature (T_{C}) shifts toward lower temperature with increasing content of Ca. The theory of ferroelectric soft mode has been developed to illuminate the relationship between the structure and properties of the polycrystal.
