Abstract |
We study the process of energy conversion from overcritical electric field into electron-positron-photon plasma. For this goal we solve numerically the system of coupled Vlasov-Boltzmann equation for pairs and photons assuming the system is homogeneous and anisotropic. Interactions between pairs and photons are described by exact QED collision terms. We evidence several epochs of this energy conversion. Firstly pair creation occurs by Schwinger vacuum breakdown. Secondly back reaction of pairs produced and accelerated results in plasma oscillations. Thirdly photons are produced by electron-positron annihilation. Finally particle interactions result in thermal electron-positron-photon plasma. Their characteristic time-scales are discussed for different initial values of electric field. |
