Measuring the Boiling Point of the Vacuum of Quantum Electrodynamics

Dra. (c) Natalia Tapia, Universidad de Santiago


The success of the theory for electrons and photons, QED, is known. However some of the predictions of its observables are not accesible by mean of perturbation theory. An example of this is the rate of spontaneous pair production in a strong static electric field, which requires colliding beams of gamma rays reaching the Schwinger critical field (1.3*10^(18) V/m). As this limit lies far way from what can be produced on laboratories we propose an alternative way to measure the critical field by the decaying of a high energy Bremsstrahlung photon in a high intensity laser field into pairs of electron positron, which would allow us the measure the boiling point of vacuum of QED.
