The third chapter is the main work . we discuss how to deal with the polaronic effect by the feynman path integral 第三章作為論文的主題,我們詳細(xì)論述處理極化子理論的feynman路徑積分方法。
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相位依賴于被中子圍繞的電荷密度,在這個意義上aharonov cosher效應(yīng)是幾何的。
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 我們以二維非對易空間的手征qcd _ 2模型為例討論了非對易規(guī)范理論中的手征反常問題。
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 為加深對水平網(wǎng)絡(luò)中非角聯(lián)旁側(cè)支路風(fēng)流逆轉(zhuǎn)機(jī)理的認(rèn)識,對運(yùn)動方程中對流項(xiàng)的沿程積分與冷抽力的聯(lián)系與區(qū)別進(jìn)行了討論。
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極化子哈密頓中電子和光學(xué)聲子耦合強(qiáng)弱不同,有著不同的研究方法,諸如微擾論,變分法, green函數(shù)方法,以及feynman的路徑積分方法,這些方法處理問題的范圍是不同的。
