Název v původním jazyce

The effect of the electron's spin magnetic moment on quantum radiation in strong electromagnetic fields

Popis výsledku v původním jazyce

Ultra-intense laser pulses can create sufficiently strong fields to probe quantum electrodynamics effects in a novel regime. By colliding a 60 GeV electron bunch with a laser pulse focussed to the maximum achievable intensity of 10(23) W cm(-2), we can reach fields much stronger than the critical Schwinger field in the electron rest frame. When the ratio of these fields chi(e)>> 1 we find that the hard ( >25 GeV) radiation from the electron has a substantial contribution from spin-light. 33% more photons are produced above this energy due to spin-light, the radiation resulting from the acceleration of the electron's intrinsic magnetic moment. This increase in high-energy photons results in 14% more positrons produced with energy above 25 GeV. Furthermore, the enhanced photon production due to spin-light results in a 46% increase in the electron recoil radiation reaction. These observable signatures provide a potential route to observing spin-light in the strongly quantum regime ( chi(e)>> 1) for the first time.
