The third chapter is the main work . we discuss how to deal with the polaronic effect by the feynman path integral 第三章作为论文的主题,我们详细论述处理极化子理论的feynman路径积分方法。
The aharonov - casher effect in the noncommutative space is considered . in order to obtain the shift in the interference pattern , we analyzed the path integral formulation Ahoronov cosher主出, ahoronov cosher相位依赖于被中子围绕的电荷密度,在这个意义上aharonov cosher效应是几何的。
Chiral anomaly in noncommutative field theory renewed the physist ' s interest in the past years . we mainly study the chiral anomaly of two dimensional non - commutative chiral qcd2 model using fujikawa ' s path integral approach 我们以二维非对易空间的手征qcd _ 2模型为例讨论了非对易规范理论中的手征反常问题。
In order to gain a better understanding of the mechanism of airflow reversal in a non - diagonal airway of a horizontal network , the relationship and difference between the path integral of the convection item contained in the movement equation and the pressure increase induced by cooling of fume were discussed 为加深对水平网络中非角联旁侧支路风流逆转机理的认识,对运动方程中对流项的沿程积分与冷抽力的联系与区别进行了讨论。
Because there exists the different strength of coupling between the electron and phonon , there have some different ways , such as the perturbation theory , variation theory , green function theory and the feynman " s path integral approach . they can be appropriately used in different area Frohlich极化子哈密顿中电子和光学声子耦合强弱不同,有着不同的研究方法,诸如微扰论,变分法, green函数方法,以及feynman的路径积分方法,这些方法处理问题的范围是不同的。
