带电粒子在静电和磁场中具有朗道能级和真空中的隧道态。利用物理学的瞬子方法。Rev. D 65, 105002(2002)，我们得到了旋量QED和标量QED中对产率的公式，它对所有朗道能级求和，完全恢复了众所周知的结果。计算了有限范围的电场和索特势的成对产生率，两者都具有恒定的磁场，并显示出有限大小的效应。
Charged particles in static electric and magnetic fields have Landau levels and tunneling states from the vacuum. Using the instanton method of Phys. Rev. D 65, 105002 (2002), we obtain the formulas for the pair-production rate in spinor and scalar QED, which sum over all Landau levels and recover exactly the well-known results. The pair-production rates are calculated for an electric field of finite extent, and for the Sauter potential, both with a constant magnetic field also present, and are shown to have finite-size effects.
