峰值电场产生粒子

Particle creation by peak electric field

T. C. Adorno, S. P. Gavrilov, D. M. Gitman

摘要:

被认为是由所谓的峰值电场的粒子创建。后一场是两个指数部分的组合,一个指数增加,另一个指数减少。我们找到了狄拉克方程的精确解与考虑适当的渐近条件下的领域和计算粒子创造效应的所有特性,特别是,微分平均数创建的粒子,创建的粒子总数,和真空的概率保持真空。详细讨论了特征渐近制度,并与纯渐近衰减场进行了比较。

英文摘要:

The particle creation by the so-called peak electric field is considered. The latter field is a combination of two exponential parts, one exponentially increasing and another exponentially decreasing. We find exact solutions of the Dirac equation with the field under consideration with appropriate asymptotic conditions and calculate all the characteristics of particle creation effect, in particular, differential mean numbers of created particle, total number of created particles, and the probability for a vacuum to remain a vacuum. Characteristic asymptotic regimes are discussed in detail and a comparison with the pure asymptotically decaying field is considered.
