我们研究来自超临界库仑势和带电黑洞的带电玻色子的自发发射。我们通过在渐进边界处的 Jost 函数上应用隧道边界条件，找到了 Bogoliubov 变换的精确发射率。超临界库仑势中带电玻色子的发射速率随着超原子的电荷 Zα < 1/2 和玻色子能量的增加而增加，但对于大角动量则受到抑制。我们讨论超原子和带电黑洞发射带电玻色子的物理含义。
We study the spontaneous emission of charged bosons from supercritical Coulomb potentials and charged black holes. We find the exact emission rate from the Bogoliubov transformation by applying the tunneling boundary condition on the Jost functions at the asymptotic boundaries. The emission rate for charged bosons in the supercritical Coulomb potential increases as the charge Zα < 1/2 of the superatom and the energy of the bosons increase, but is suppressed for large angular momenta. We discuss physical implications of the emission of charged bosons from superatoms and charged black holes.
