p perturbation method, the dressed bands of semiconductors have been investigated using the renormalized effective mass approximation, dressed-band approximation and exact Floquet matrix method.
最后,主要采用(?)微扰方法,并利用缀饰带近似、重整化有效质量近似、以及Floquet矩阵方法研究了激光缀饰下半导体三能带模型。
In the Lorentz invariant coupling model of the interaction between nucleon N(antinucleon) and neutral meson π~0,the authors thoroughly analyze the moment regularization of N-loop propagator in the moment renormalization,and find that traditional minus-dividing can be substituted by the matrix function expanding.
采用核子N(反核子N-)与中性介子π0相互作用的Lorentz不变耦合模型,对N-N-圈图传播子在“动量重整化方案”中的“动量正规化”作了深入细致的分析与考证,发现可以采用“矩阵函数展开法”来替代通常采用的“传统减除法”,并由此对N-N-圈图传播子函数中的“发散量”与“有限量”作了十分简捷有效的分离,获得了“重整化有限量”的一个具有“明确计算含义”的表达式。
In this paper,renormalization mass of the surface polaron in polar crystals were studied.
讨论了极性半导体中表面极化子重正化质量的性质。
