S-matrix study on alignment dependence of single ionization of molecular ions with different active orbitals
收藏 引用
Chinese Physics B 2010年 第6期19卷 254-258页
作者: 李燕 贾欣燕 杨世平 李卫东 陈京 Department of Physics Hebei Normal University Institute of Applied Physics and Computational Mathematics Institute of Theoretical Physics and Department of Physics Shanxi University Center for Applied Physics and Technology Peking University
The single ionization rate of the diatomic molecular ion H2^+ with different active orbitals in an intense field is studied by using S-matrix theory. Our results show that the orientation-dependent single ionization ... 详细信息

Rank-width and Well-quasi-ordering of Skew-symmetric Matrices. (extended abstract)
收藏 引用
Electronic Notes in Discrete mathematics 2005年 22卷 281-285页
作者: Oum, Sang-il Program in Applied and Computational Mathematics Princeton University Princeton NJ 08540 United States
Robertson and Seymour prove that a set of graphs of bounded tree-width is well-quasi-ordered by the graph minor relation. By extending their methods to matroids, Geelen, Gerards, and Whittle prove that a set of matroi... 详细信息

computational test of the renormalization group theory of turbulence
收藏 引用
Journal of Scientific Computing 1988年 第2期3卷 139-147页
作者: Yakhot, Victor Orszag, Steven A. Panda, Raj Program in Applied and Computational Mathematics Princeton University Princeton 08544 New Jersey United States
The results of numerical simulations of random-force-driven Navier-Stokes turbulence designed to test predictions of the renormalization group theory of turbulence are presented. By specially choosing the random force... 详细信息
