摘要:

将细胞膜各层的等离子体激元振荡视为准粒子,引入一个简单的膜集体电荷激发模型,考虑了两层间等离子体激元-等离子体激元相互作用的表面有效势。利用Bogoliubov变换方法,我们很容易地得到了等离子体激元振荡频率与波数$k$和膜厚度$d$的函数关系式,这些频率的量级为$\sqrt{kd}$。我们的结果与E.马诺萨基斯

英文摘要:

Considering the plasmon oscillation of each layer of the cell membranes as a quasi-particle, we introduce a simple model for the membrane collective charge excitations, take into account the surface effective potential of the plasmon-plasmon interaction between two layers. By using the useful Bogoliubov transformation method, we easily obtained the expressions of the frequencies of plasmon oscillations as a function of wave-number $k$ and membrane thickness $d$, magnitude of these frequencies is in the order of $\sqrt{kd}$. Our results are in good agreement with ones obtained by E. Manousakis.
