The metastable behavior of the three-dimensional stochastic Ising model(Ⅱ)
《Science China Mathematics》1997年第11期1129-1135,共7页陈大岳 冯建峰 钱敏平 
Project supported in part by a Postdoctoral Fellowship from the State Education Commission of China, and by the National Natural Science Foundation of China, the Tianyuan Foundation and the National 863 Project.
The metastable behavior of the stochastic Ising model is studied in a finite three-dimensional torus,in the limit as the temperature goes to zero.The so-called critical droplet is determined,a clear view of the passag...

Phenomenological theory of surface effects in ferroelectrics and its relationship with transverse Ising model
《Science China Mathematics》1997年第1期67-75,共9页钟维烈 王玉国 张沛霖 曲保东 
Project partly supported by the Laboratory of Function Inorganic Materials of the Chinese Academy of Sciences.
The relationship between the transverse field Ising model and the Landau phenomenological theory for ferroelectrics is analyzed, and the Landau free energy expression for ferroelectrics having surfaces is derived. It ...

The Energy-Spin Correlation Function of 2-D Ising Model With External Magnetic Field for T>T_c~*
《Science China Mathematics》1993年第4期449-458,共10页赵宏康 阎沐霖 
Project supported in part by the National Natural Science Foundation of China.
Under the scaling limit, i.e. T→T_c+, H→O, R→∞, where h=const. H|T-T_c|^(-15/8) is fixed and small, while r=R|T-T_c|is fixed and large, we investigate the energy-spin correlation function <σ_(M1), _(N1)σ_(M2), _...
