Titre |
Vacuum birefringence in strong-field quantum electrodynamics using an effective approach |
|
Résumé |
The description of quantum phenomena in strong background electromagnetic fields,
although starting at least in the 1930s with the Heisenberg-Euler effective
theory, has gained growing attention over the last two decades. The recent
development of ultra-high intensity laser facilities is making the prospect of
testing this regime of QED in the laboratory reality. One of the strong-field
phenomena that have yet to be observed, vacuum birefringence is the result of the
interaction between a photon and the vacuum, behaving as a polarized medium when
filled with a strong background. After providing a broad presentation of the key
ideas of SFQED, I will focus on a recent study using an effective approach to
describe vacuum birefringence in background plane waves, showing that the vacuum
can behave as a chiral medium. |
