从势阱中抽运电子-正电子对

Pump Electron-Positron Pairs from Potential Well

Qiang Wang, Jie Liu, Li-Bin Fu

摘要:

本文证明了在一维势阱中,正负电子对可以以恒定的产生率从势阱的深度或宽度振荡的情况下被无限地抽运。嵌入狄拉克海中的束缚态可以被拉出来,推到正连续区,成为散射态。在静态超临界势阱中,控制电子对产生饱和的泡利块可以被电子的射出所打破。我们发现,宽度振荡模式是更有效的深度振荡模式。在绝热极限下,电子对数作为振荡上边界的函数,将揭示束缚态的分裂。

英文摘要:

In this paper we show that electron-positron pairs can be pumped inexhaustibly with a constant production rate from the one dimensional potential well with oscillating depth or width. Bound states embedded in the the Dirac sea can be pulled out and pushed to the positive continuum, and become scattering states. Pauli block, which dominant the saturation of pair creation in the static super-critical potential well, can be broken by the ejection of electrons. We find that the width oscillating mode is more efficient that the depth oscillating mode. In the adiabatic limit, pair number as a function of upper boundary of the oscillating, will reveal the diving of the bound states.
