Fermion Particle Production in Dynamical Casimir Effect in a Three Dimensional Box

M. R. Setare, A. Seyedzahedi

摘要:

本文研究了三维盒子中费米子的产生问题。我们提出了一个合适的波函数,它满足该几何条件下的狄拉克方程与MIT袋模型的边界条件。我们认为墙壁的盒子有动态的,并介绍了时间演化的量子化领域扩大它的“瞬时基础”。我们解释了如何获得产生的粒子的平均数。在这方面,我们找到Bogliubove系数。我们考虑一个振荡,并确定不同模式之间的耦合条件,可以满足取决于腔的频谱。假设参数共振的情况下,我们得到一个表达式的平均数产生的费米子在每个模式的振荡和他们的动态卡西米尔能量。

英文摘要:

In this paper we investigate the problem of fermion creation inside a three dimensional box. We present an appropriate wave function which satisfies the Dirac equation in this geometry with MIT bag model boundary condition. We consider walls of the box to have dynamic and introduce the time evolution of the quantized field by expanding it over the 'instantaneous basis'. We explain how we can obtain the average number of particles created. In this regard we find the Bogliubove coefficients. We consider an oscillation and determine the coupling conditions between different modes that can be satisfied depending on the cavity's spectrum. Assuming the parametric resonance case we obtain an expression for the mean number of created fermions in each mode of an oscillation and their dynamical Casimir energy.
