强电场和磁场中真空快速衰变为粒子对

Fast vacuum decay into particle pairs in strong electric and magnetic fields

Yoshimasa Hidaka, Takumi Iritani, Hideo Suganuma

摘要:

我们讨论了在强电场和磁场中的费米子对产生。指出在无质量费米子的情况下,在强电场和磁场中,单位时间和单位体积的真空持续几率为零,而在无磁场时,真空持续几率为有限。来自最低朗道能级(LLL)的贡献主导了这种现象。我们还讨论了真空衰减的动力学,使用一个有效的理论的LLL投影,考虑到反反应。

英文摘要:

We discuss fermion pair productions in strong electric and magnetic fields. We point out that, in the case of massless fermions, the vacuum persistency probability per unit time and volume is zero in the strong electric and magnetic fields, while it is finite when the magnetic field is absent. The contribution from the lowest Landau level (LLL) dominates this phenomenon. We also discuss dynamics of the vacuum decay, using an effective theory of the LLL projection, taking into account the back reaction.
