Axion assisted Schwinger effect / Domcke, Valerie ; Ema, Yohei ; Mukaida, Kyohei
We point out an enhancement of the pair production rate of charged fermions in a strong electric field in the presence of time dependent classical axion-like background field, which we call axion assisted Schwinger effect. [...]
