A revised iterative method based on Green function defined by quadratures along a single trajectory isproposed to solve the low-lying quantum wave function for Schrdinger *** a new expression of theperturbed energy is obtained,which is much simpler than the traditional *** method is applied to solve theunharmonic oscillator *** revised iteration procedure gives exactly the same result as those based on thesingle trajectory quadrature method.A comparison of the revised iteration method to the old one is made using theexample of Stark *** obtained results are consistent to each other after making power expansion.

According to A. B. Migdal’s prediction that a pion condensate should exist in ordinaryfinite nuclei, a nucleon density modulation due to pion condensate has been obtained frompseudovector pion nucleon coupling and phenomenological effective repulsion *** on the nucleon density modulation, we study the effects of pion condensate in somenuclear phenomena, such as high energy particle nucleus scattering, X-ray energy spectrumof muonic atom and nuclear binding *** results strongly indicate that there aresome sufficient opportunities in these processes for pion condensate to manifest itself andthe condensate could help us to improve the agreement between theory and experiments formany processes.

Color Superconductivity at Moderate Baryon Density

CCAST“色超导研究的新进展”研讨会

作者： Mei Huang~(?) 1. Institute for theoretical physics, J. W. Goethe University, Frankfurt am Main, Germany 2. physics Department, Tsinghua University, {3., china

＜正＞These lectures focus on the two-flavor color superconducting phase at moderate baryon density. In order to simultaneously investigate the chiral phase transition and the color superconducting phase transition, the Nambu-Gorkov formalism is extended to treat the quark-antiquark and diquark condensates on an equal footing. The competition between the chiral condensate and the diquark condensate is analyzed. The cold dense charge neutral twoflavor quark system is investigated in detail. Under the local charge neutrality condition, the ground state of two-flavor quark matter is sensitive to the coupling strength in the diquark channel. When the diquark coupling strength is around the value obtained from the Fierz transformation or from fitting the vacuum bayron mass, the ground state of charge neutral two-flavor quark matter is in a thermal stable gapless 2.C （g2.C） phase. The unusual properties at zero as well as nonzero temperatures and the chromomagnetic properties of the g2.C phase are reviewed. Under the global charge neutrality condition, assuming the surface tension is negligible, the mixed phase composed of the regular 2.C phase and normal quark matter is more favorable than the g2.C phase. A hybrid nonstrange neutron star is constructed.

The subsolar magnetopause is the boundary of solar wind and the Earth’s magnetosphere where reduced solar wind dynamic pressure is equal to the magnetic pressure of the Earth’s outer magnetosphere. We use a global MHD model to estimate the ratio （f） of the compressed magnetic field just inside the subsolar magnetopause to the purely dipolar magnetic field. We also compared our numerical results with a similar work by Shue with the THEMIS data. Our results show that the ratio f is linearly proportional to the subsolar magnetopause standoff distance （r0） for both northward and southward interplanetary magnetic field, which in property is consistent with Shue’s result but the proportionality constant is smaller, although previous theoretical studies show that the ratio f is nearly independent of the subsolar standoff distance. The global model results also show that the ratio f is smaller for the southward IMF under the same r0 and the proportionality constant for the southward IMF is larger than that for the northward IMF. Both conclusions agree with statistical results from observations by Shue.

The sequence of the rice genome holds fundamental information for its biology, including physiology, genetics, development, and evolution, as well as information on many beneficial phenotypes of economic significance. Using a "whole genome shotgun" approach, we have pro-duced a draft rice genome sequence of Oryza sativa ssp. in-dica, the major crop rice subspecies in china and many other regions of Asia. The draft genome sequence is constructed from over 4.3.million successful sequencing traces with an accumulative total length of 2.14.9 Mb. The initial assembly of the non-redundant sequences reached 409.76 Mb in length, based on 3.3. million successful sequencing traces with a total length of 1797.4 Mb from an indica variant cultivar 93.11, giving an estimated coverage of 95.2.% of the rice genome with an average base accuracy of higher than 99%. The coverage of the draft sequence, the randomness of the sequence distribution, and the consistency of BIG-ASSEM-BLER, a custom-designed software package

＜正＞ The Debye screening masses of the σ,ωand neutral p mesons and the photon are calculated in the relativistic mean-field approximation. As the density of the nucleon increases, all the screening masses of mesons increase. It shows a different result with Brown-Rho scaling, which implies a reduction in the mass of all the mesons in the nuclear matter except the pion. Replacing the masses of the mesons with their corresponding screening masses in Walecka-1 model, five saturation properties of the nuclear matter are fixed reasonably, and then a density-dependent relativistic mean-field model is proposed without introducing the non-linear self-coupling terms of mesons.
