Abstract:We show that electron-positron pair production from the vacuum is possible via the strong Coulomb fields generated by micro-bubble implosions induced by ultra-high intensity lasers. Even in the case where the Coulomb fields are lower than the pair creation threshold, externally injected high energy electrons or photons could be used to generate pairs.
Keywords:Pair creation  Vacuum  Micro-bubble implosion  Ultra-high intensity lasers
