实验室gamma-ray脉冲星

Laboratory gamma-ray pulsar

Andrei Gruzinov

摘要:

伽马射线闪烁的机制可能在实验室中重现。这一论断得到了三个观测结果的支持:(1)当测试电子辐射过阻尼时,适当聚焦几个脉宽的光激光产生一个所谓的阿斯特丽德区的电磁场;(ii)该电磁场的Goldreich-Julian数密度(光功率几乎完全转换成γ射线所需的元电荷的数密度)与固体中的电子数密度相当;(iii)在约$50$ PW以上,不需要外部电子源--电荷将由对产生雪崩产生。

英文摘要:

The mechanism by which gamma-ray pulsars shine might be reproducible in a laboratory. This claim is supported by three observations: (i) properly focusing a few PW optical laser gives an electromagnetic field in the so-called Aristotelian regime, when a test electron is radiation-overdamped; (ii) the Goldreich-Julian number density of this electromagnetic field (the number density of elementary charges needed for a nearly full conversion of optical power into gamma-rays) is of order the electron number density in a solid; (iii) above about $50$PW, the external source of electrons is not needed -- charges will be created by a pair production avalanche.
